-# This file documents the option groups EGLIBC currently supports, in
-# a format akin to the Linux Kconfig system's.  The syntax may change
-# over time.
-#
-# An entry of the form:
-#
-#   config OPTION_GROUP_NAME
-#       bool "one-line explanation of what this option group controls"
-#       help
-#           Multi-line help explaining the option group's meaning in
-#           some detail, terminated by indentation level.
-#
-# defines an option group whose variable is OPTION_GROUP_NAME, with
-# meaningful values 'y' (enabled) and 'n' (disabled).  The
-# documentation is formatted to be consumed by some sort of
-# interactive configuration interface, but EGLIBC doesn't have such an
-# interface yet.
-#
-# An option may have a 'depends' line, indicating which other options
-# must also be enabled if this option is.  At present, EGLIBC doesn't
-# check that these dependencies are satisfied.
-#
-# Option group variables get their default values from the file
-# 'option-groups.defaults', in the top directory of the EGLIBC source
-# tree.  By default, all EGLIBC option groups are enabled --- their
-# variables are set to 'y'.
-#
-# After including 'option-groups.defaults', the EGLIBC make machinery
-# includes the file 'option-groups.config' from the top of the build
-# tree, if it is present.  Developers can place assignments to option
-# group variables in that file to override the defaults.  For example,
-# to disable an option group, place a line of the form:
-#
-#    OPTION_GROUP_NAME = n
-#
-# in 'option-groups.config' at the top of your build tree.  To
-# explicitly enable an option group, you may also write:
-#
-#    OPTION_GROUP_NAME = y
-#
-# although this simply reestablishes the value already set by
-# 'option-groups.defaults'.

-config KEMBTK_EGLIBC_OPTION_EGLIBC_BACKTRACE
-	default y
-	bool "Functions for producing backtraces"
-	help
-		This option group includes functions for producing a list of
-		the function calls that are currently active in a thread, from
-		within the thread itself.  These functions are often used
-		within signal handlers, to produce diagnostic output.
-
-		This option group includes the following functions:
-
-		backtrace
-		backtrace_symbols
-		backtrace_symbols_fd
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_BSD
-	bool "BSD-specific functions, and their compatibility stubs"
-	help
-		This option group includes functions specific to BSD kernels.
-		A number of these functions have stub versions that are also
-		included in libraries built for non-BSD systems for
-		compatibility.
-
-		This option group includes the following functions:
-
-		 chflags
-		 fchflags
-		 lchmod
-		 revoke
-		 setlogin
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_CXX_TESTS
-	bool "Tests that link against the standard C++ library."
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
-	depends on KEMBTK_EGLIBC_OPTION_EGLIBC_LIBM
-	help
-		This option group does not include any C library functions;
-		instead, it controls which EGLIBC tests an ordinary 'make
-		tests' runs.  With this group disabled, tests that would
-		normally link against the standard C++ library are not
-		run.
-
-		The standard C++ library depends on the math library 'libm' and
-		the wide character I/O functions included in EGLIBC.  If those
-		option groups are disabled, this test must also be disabled.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_LIBM
-	default y
-	bool "libm (math library)"
-	help
-		This option group includes the 'libm' library, containing
-		mathematical functions.  If this option group is omitted, then
-		an EGLIBC installation does not include shared or unshared versions
-		of the math library.
-
-		Note that this does not remove all floating-point related
-		functionality from EGLIBC; for example, 'printf' and 'scanf'
-		can still print and read floating-point values with this option
-		group disabled.
-
-		Note that the ISO Standard C++ library 'libstdc++' depends on
-		EGLIBC's math library 'libm'.  If you disable this option
-		group, you will not be able to build 'libstdc++' against the
-		resulting EGLIBC installation.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_CHARSETS
-	bool "iconv/gconv character set conversion libraries"
-	help
-		This option group includes support for character sets other
-		than ASCII (ANSI_X3.4-1968) and Unicode and ISO-10646 in their
-		various encodings.  This affects both the character sets
-		supported by the wide and multibyte character functions, and
-		those supported by the 'iconv' functions.
-
-		With this option group disabled, EGLIBC supports only the
-		following character sets:
-
-		ANSI_X3.4         - ASCII
-		ANSI_X3.4-1968
-		ANSI_X3.4-1986
-		ASCII
-		CP367

-config KEMBTK_EGLIBC_OPTION_EGLIBC_ENVZ
-	bool "Functions for handling envz-style environment vectors."
-	help
-		This option group contains functions for creating and operating
-		on envz vectors.  An "envz vector" is a vector of strings in a
-		contiguous block of memory, where each element is a name-value
-		pair, and elements are separated from their neighbors by null
-		characters.
-
-		This option group includes the following functions:

-		networking; aliases; public keys; and so on) consult the
-		'/etc/nsswitch.conf' configuration file to decide how to handle
-		queries.
-
-		With this option group disabled, EGLIBC uses a fixed list of
-		services to satisfy queries on each database, as requested by
-		configuration files specified when EGLIBC is built.  Your
-		'option-groups.config' file must set the following two
-		variables:
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	string "Alternate file for nsswitch.conf (see below help please)"
-	help
-		Set this to the name of a file whose contents observe the
-		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
-		EGLIBC build process parses this file just as EGLIBC would
-		at run time if OPTION_EGLIBC_NSSWITCH were enabled, and
-		produces a C library that uses the nsswitch service
-		libraries to search for database entries as this file
-		specifies, instead of consulting '/etc/nsswitch.conf' at run
-		time.
-
-		This should be an absolute filename.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		The EGLIBC source tree includes a sample configuration file
-		named 'nss/fixed-nsswitch.conf'; for simple configurations,
-		you will probably want to delete references to databases not
-		needed on your system.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	string "Alternate nss/fixed-nsswitch.functions file (see below help please)"
-	help
-		The EGLIBC build process uses this file to decide which
-		functions to make available from which service libraries.
-		The file 'nss/fixed-nsswitch.functions' serves as a sample
-		configuration file for this setting, and explains its syntax
-		and meaning in more detail.
-
-		This should be an absolute file name.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		Be sure to mention each function in each service you wish to
-		use.  If you do not mention a service's function here, the
-		EGLIBC database access functions will not find it, even if
-		it is listed in the OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-		file.
-
-		In this arrangement, EGLIBC will not use the 'dlopen' and
-		'dlsym' functions to find database access functions.  Instead,
-		libc hard-codes references to the service libraries' database
-		access functions.  You must explicitly link your program
-		against the name service libraries (those whose names start
-		with 'libnss_', in the sysroot's '/lib' directory) whose
-		functions you intend to use.  This arrangement helps
-		system-wide static analysis tools decide which functions a
-		system actually uses.
-
-		Note that some nsswitch service libraries require other option
-		groups to be enabled; for example, the OPTION_EGLIBC_INET
-		option group must be enabled to use the 'libnss_dns.so.2'
-		service library, which uses the Domain Name System network
-		protocol to answer queries.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_SPAWN
-	bool "Support for POSIX posix_spawn functions"

-		charmap files.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_STREAMS
-	bool "Support for accessing STREAMS."
-		help
-		This option group includes functions for reading and writing
-		messages to and from STREAMS.  The STREAMS interface provides a
-		uniform mechanism for implementing networking services and other
-		character-based I/O.  (STREAMS are not to be confused with

-config KEMBTK_EGLIBC_OPTION_EGLIBC_LOCALE_CODE
-	bool "Locale functions"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
-	help
-		This option group includes locale support functions, programs,
-		and libraries.  With OPTION_EGLIBC_LOCALE_FUNCTIONS disabled,
-		EGLIBC supports only the 'C' locale (also known as 'POSIX'),
-		and ignores the settings of the 'LANG' and 'LC_*' environment
-		variables.
-
-		With OPTION_EGLIBC_LOCALE_CODE disabled, the following

-
-		 duplocale   localeconv  nl_langinfo    rpmatch  strfmon_l
-		 freelocale  newlocale   nl_langinfo_l  strfmon  uselocale
-
-		Furthermore, only the LC_CTYPE and LC_TIME categories of the
-		standard "C" locale are available.
-
-		The OPTION_EGLIBC_CATGETS option group depends on this option
-		group; if you disable OPTION_EGLIBC_LOCALE_CODE, you must also
-		disable OPTION_EGLIBC_CATGETS.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_CATGETS
-	bool "Functions for accessing message catalogs"
-	depends on KEMBTK_EGLIBC_OPTION_EGLIBC_LOCALE_CODE

-		This option group depends on the OPTION_EGLIBC_LOCALE_CODE
-		option group; if you disable that, you must also disable this.
-
-config KEMBTK_EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
-	bool "Input and output functions for wide characters"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
-	help
-		This option group includes functions for reading and writing
-		wide characters to and from <stdio.h> streams.

-		fgetws_unlocked           getwchar_unlocked
-		fputwc_unlocked           putwc_unlocked
-		fputws_unlocked           putwchar_unlocked
-
-		Note that the GNU standard C++ library, 'libstdc++.so', uses
-		some of these functions; you will not be able to link or run
-		C++ programs if you disable this option group.
-
-		This option group also affects the behavior of the following
-		functions:
-
-		fdopen
-		fopen
-		fopen64
-		freopen
-		freopen64
-
-		These functions all take an OPENTYPE parameter which may
-		contain a string of the form ",ccs=CHARSET", indicating that
-		the underlying file uses the character set named CHARSET.
-		This produces a wide-oriented stream, which is only useful
-		when the functions included in this option group are present.
-		If the user attempts to open a file specifying a character set
-		in the OPENTYPE parameter, and EGLIBC was built with this
-		option group disabled, the function returns NULL, and sets
-		errno to EINVAL.
-
-config KEMBTK_EGLIBC_OPTION_POSIX_REGEXP
-	default y
-	bool "Regular expressions"
-	help
-		This option group includes the POSIX regular expression
-		functions, and the associated non-POSIX extensions and
-		compatibility functions.
-
-		With OPTION_POSIX_REGEXP disabled, the following functions are
-		omitted from libc:
-
-		re_comp                 re_max_failures         regcomp

-config KEMBTK_EGLIBC_OPTION_POSIX_REGEXP_GLIBC
-	bool "Regular expressions from GLIBC"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_REGEXP
-	help
-		This option group specifies which regular expression
-		library to use.  The choice is between regex
-		implementation from GLIBC and regex implementation from
-		libiberty.  The GLIBC variant is fully POSIX conformant and
-		optimized for speed; regex from libiberty is more than twice
-		as small while still is enough for most practical purposes.

-
-		Note that this does not remove all floating-point related

-
-		Note that the ISO Standard C++ library 'libstdc++' depends on

-		Libmemusage library buffers the profiling data in memory
-		before writing it out to disk.  By default, the library
-		allocates 1.5M buffer, which can be substantial for some
-		systems.  OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE option
-		allows to change the default buffer size.  It specifies
-		the number of entries the buffer should have.
-		On most architectures one buffer entry amounts to 48 bytes,

-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH

-	help
-		This option group includes support for the 'nsswitch' facility.
-		With this option group enabled, all EGLIBC functions for
-		accessing various system databases (passwords and groups;
-		networking; aliases; public keys; and so on) consult the
-		'/etc/nsswitch.conf' configuration file to decide how to handle
-		queries.
-
-		With this option group disabled, EGLIBC uses a fixed list of
-		services to satisfy queries on each database, as requested by
-		configuration files specified when EGLIBC is built.  Your
-		'option-groups.config' file must set the following two
-		variables:
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-	string "Alternate file for nsswitch.conf (see below help please)"
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	help
-		Set this to the name of a file whose contents observe the
-		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
-		EGLIBC build process parses this file just as EGLIBC would
-		at run time if OPTION_EGLIBC_NSSWITCH were enabled, and
-		produces a C library that uses the nsswitch service
-		libraries to search for database entries as this file
-		specifies, instead of consulting '/etc/nsswitch.conf' at run
-		time.
-
-		This should be an absolute filename.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		The EGLIBC source tree includes a sample configuration file
-		named 'nss/fixed-nsswitch.conf'; for simple configurations,
-		you will probably want to delete references to databases not
-		needed on your system.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS
-	string "Alternate nss/fixed-nsswitch.functions file (see below help please)"
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	help
-		The EGLIBC build process uses this file to decide which
-		functions to make available from which service libraries.
-		The file 'nss/fixed-nsswitch.functions' serves as a sample
-		configuration file for this setting, and explains its syntax
-		and meaning in more detail.
-
-		This should be an absolute file name.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		Be sure to mention each function in each service you wish to
-		use.  If you do not mention a service's function here, the
-		EGLIBC database access functions will not find it, even if
-		it is listed in the OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-		file.
-
-		In this arrangement, EGLIBC will not use the 'dlopen' and
-		'dlsym' functions to find database access functions.  Instead,
-		libc hard-codes references to the service libraries' database
-		access functions.  You must explicitly link your program
-		against the name service libraries (those whose names start
-		with 'libnss_', in the sysroot's '/lib' directory) whose
-		functions you intend to use.  This arrangement helps
-		system-wide static analysis tools decide which functions a
-		system actually uses.
-
-		Note that some nsswitch service libraries require other option
-		groups to be enabled; for example, the OPTION_EGLIBC_INET
-		option group must be enabled to use the 'libnss_dns.so.2'
-		service library, which uses the Domain Name System network
-		protocol to answer queries.

-config KEMBTK_EGLIBC_OPTION_EGLIBC_SPAWN

-	bool "Input and output functions for wide characters"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
-	help
-		This option group includes functions for reading and writing
-		wide characters to and from <stdio.h> streams.
-
-		This option group includes the following functions:
-
-		fgetwc        fwprintf      putwchar      vwscanf
-		fgetws        fwscanf       ungetwc       wprintf

-		fputws        getwchar      vfwscanf
-		fwide         putwc         vwprintf
-
-		This option group further includes the following unlocked
-		variants of the above functions:
-
-		fgetwc_unlocked           getwc_unlocked
-		fgetws_unlocked           getwchar_unlocked
-		fputwc_unlocked           putwc_unlocked
-		fputws_unlocked           putwchar_unlocked
-
-		Note that the GNU standard C++ library, 'libstdc++.so', uses
-		some of these functions; you will not be able to link or run
-		C++ programs if you disable this option group.
-
-		This option group also affects the behavior of the following
-		functions:
-
-		fdopen
-		fopen
-		fopen64
-		freopen
-		freopen64
-
-		These functions all take an OPENTYPE parameter which may
-		contain a string of the form ",ccs=CHARSET", indicating that
-		the underlying file uses the character set named CHARSET.
-		This produces a wide-oriented stream, which is only useful
-		when the functions included in this option group are present.
-		If the user attempts to open a file specifying a character set
-		in the OPENTYPE parameter, and EGLIBC was built with this
-		option group disabled, the function returns NULL, and sets
-		errno to EINVAL.

-config KEMBTK_EGLIBC_OPTION_EGLIBC_LOCALE_CODE
-	bool "Locale functions"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
-	help
-		This option group includes locale support functions, programs,
-		and libraries.  With OPTION_EGLIBC_LOCALE_FUNCTIONS disabled,
-		EGLIBC supports only the 'C' locale (also known as 'POSIX'),
-		and ignores the settings of the 'LANG' and 'LC_*' environment
-		variables.
-
-		With OPTION_EGLIBC_LOCALE_CODE disabled, the following
-		functions are omitted from libc:
-
-		duplocale   localeconv  nl_langinfo    rpmatch  strfmon_l
-		freelocale  newlocale   nl_langinfo_l  strfmon  uselocale
-
-		Furthermore, only the LC_CTYPE and LC_TIME categories of the
-		standard "C" locale are available.
-
-		The OPTION_EGLIBC_CATGETS option group depends on this option
-		group; if you disable OPTION_EGLIBC_LOCALE_CODE, you must also
-		disable OPTION_EGLIBC_CATGETS.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_CATGETS
-	bool "Functions for accessing message catalogs"
-	depends on KEMBTK_EGLIBC_OPTION_EGLIBC_LOCALE_CODE
-	help
-		This option group includes functions for accessing message
-		catalogs: catopen, catclose, and catgets.
-
-		This option group depends on the OPTION_EGLIBC_LOCALE_CODE
-		option group; if you disable that, you must also disable this.
-
-config KEMBTK_EGLIBC_OPTION_POSIX_REGEXP
-	bool "Regular expressions"
-	default y
-	help
-		This option group includes the POSIX regular expression
-		functions, and the associated non-POSIX extensions and
-		compatibility functions.
-
-		With OPTION_POSIX_REGEXP disabled, the following functions are
-		omitted from libc:
-
-		re_comp                 re_max_failures         regcomp
-		re_compile_fastmap      re_search               regerror

-		re_match_2              re_syntax_options
-
-		Furthermore, the compatibility regexp interface defined in the
-		<regexp.h> header file, 'compile', 'step', and 'advance', is
-		omitted.
-
-config KEMBTK_EGLIBC_OPTION_POSIX_REGEXP_GLIBC
-	bool "Regular expressions from GLIBC"
-	depends on KEMBTK_EGLIBC_OPTION_POSIX_REGEXP
-	help
-		This option group specifies which regular expression
-		library to use.  The choice is between regex
-		implementation from GLIBC and regex implementation from
-		libiberty.  The GLIBC variant is fully POSIX conformant and
-		optimized for speed; regex from libiberty is more than twice
-		as small while still is enough for most practical purposes.

-		of the math library.
-
-		Note that this does not remove all floating-point related

-		Not selecting this option group removes most of the extended and
-		double precision math functions and replaces them with wrappers
-		to the single precision couterparts.
-		Doing so greatly degrades quality of calculations carried

-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_LOCALES

-		Libmemusage library buffers the profiling data in memory
-		before writing it out to disk.  By default, the library
-		allocates 1.5M buffer, which can be substantial for some
-		systems.  OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE option
-		allows to change the default buffer size.  It specifies
-		the number of entries the buffer should have.
-		On most architectures one buffer entry amounts to 48 bytes,
-		so setting this option to the value of 512 will reduce the size
-		of the memory buffer to 24K.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	bool "Name service switch (nsswitch) support"
-	default y
-	help
-		This option group includes support for the 'nsswitch' facility.
-		With this option group enabled, all EGLIBC functions for
-		accessing various system databases (passwords and groups;
-		networking; aliases; public keys; and so on) consult the
-		'/etc/nsswitch.conf' configuration file to decide how to handle
-		queries.
-
-		With this option group disabled, EGLIBC uses a fixed list of
-		services to satisfy queries on each database, as requested by
-		configuration files specified when EGLIBC is built.  Your
-		'option-groups.config' file must set the following two
-		variables:
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-	string "Alternate file for nsswitch.conf (see below help please)"
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	help
-		Set this to the name of a file whose contents observe the
-		same syntax as an ordinary '/etc/nsswitch.conf' file.  The
-		EGLIBC build process parses this file just as EGLIBC would
-		at run time if OPTION_EGLIBC_NSSWITCH were enabled, and
-		produces a C library that uses the nsswitch service
-		libraries to search for database entries as this file
-		specifies, instead of consulting '/etc/nsswitch.conf' at run
-		time.
-
-		This should be an absolute filename.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		The EGLIBC source tree includes a sample configuration file
-		named 'nss/fixed-nsswitch.conf'; for simple configurations,
-		you will probably want to delete references to databases not
-		needed on your system.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS
-	string "Alternate nss/fixed-nsswitch.functions file (see below help please)"
-	depends on !KEMBTK_EGLIBC_OPTION_EGLIBC_NSSWITCH
-	help
-		The EGLIBC build process uses this file to decide which
-		functions to make available from which service libraries.
-		The file 'nss/fixed-nsswitch.functions' serves as a sample
-		configuration file for this setting, and explains its syntax
-		and meaning in more detail.
-
-		This should be an absolute file name.  The EGLIBC build
-		process may use it from several different working
-		directories.  It may include references to Makefile
-		variables like 'common-objpfx' (the top of the build tree,
-		with a trailing slash), or '..' (the top of the source tree,
-		with a trailing slash).
-
-		Be sure to mention each function in each service you wish to
-		use.  If you do not mention a service's function here, the
-		EGLIBC database access functions will not find it, even if
-		it is listed in the OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG
-		file.
-
-		In this arrangement, EGLIBC will not use the 'dlopen' and
-		'dlsym' functions to find database access functions.  Instead,
-		libc hard-codes references to the service libraries' database
-		access functions.  You must explicitly link your program
-		against the name service libraries (those whose names start
-		with 'libnss_', in the sysroot's '/lib' directory) whose
-		functions you intend to use.  This arrangement helps
-		system-wide static analysis tools decide which functions a
-		system actually uses.
-
-		Note that some nsswitch service libraries require other option
-		groups to be enabled; for example, the OPTION_EGLIBC_INET
-		option group must be enabled to use the 'libnss_dns.so.2'
-		service library, which uses the Domain Name System network
-		protocol to answer queries.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_RTLD_DEBUG
-	bool "Runtime linker debug print outs"
-	default y
-	help
-		This option group enables debug output of the runtime linker
-		which is activated via LD_DEBUG and LD_TRACE_PRELINKING
-		environment variables.  Disabling this option group yields
-		a smaller runtime linker binary.
-		BEWARE: Disabling this option group is likely to break
-		the `ldd' utility which may also be used by the prelinker.
-		In particular, the `--unused' ldd option will not work
-		correctly.
-
-config KEMBTK_EGLIBC_OPTION_EGLIBC_SPAWN
-	bool "Support for POSIX posix_spawn functions"
-	help
-		This option group includes the POSIX functions for executing
