	 Choose your cross compiler environment setup combination between
	 clang/llvm and GCC.

	config EMBTK_GCC_ONLY_TOOLCHAIN
		bool "GCC only"
		help
		 Choose this configuration if you want to use only traditional
		 GCC cross compiler environment.

		depends on EMBTK_ARCH_ARM || (EMBTK_ARCH_MIPS && EMBTK_TARGET_ARCH_32BITS)
		help
		 Choose this configuration if you want to use only clang/llvm
		 cross compiler environment.
		 With this configuration:
		  * All userspace packages will use clang as compiler.
		  * A bare metal gcc compiler will still be built, but you will
		  be able to only build linux kernel/u-boot etc. with this gcc.

	config EMBTK_GCC_AND_LLVM_TOOLCHAIN
		bool "clang/llvm and GCC"
		depends on EMBTK_ARCH_ARM || (EMBTK_ARCH_MIPS && EMBTK_TARGET_ARCH_32BITS)
		help
		 With this configuration you will have full clang/llvm and GGC
		 built and available to build your userspace packages.

	 Choose here which C library your toolchain will use.

	config EMBTK_CLIB_EGLIBC
		bool "eglibc"
		help
		 EGLIBC is suitable for source and binary compatibility with
		 glibc, but care is also taken to satisfy embedded systems
		 constraints.

		 see http://www.eglibc.org for more information about eglibc.

	config EMBTK_CLIB_GLIBC
		bool "glibc"
		help
		 GNU GLIBC is the well known general purpose c library found on
		 most general purpose GNU Linux distribution.

		 See http://www.gnu.org/software/libc for more information about
		 glibc.

		bool "musl"
		depends on EMBTK_TARGET_ARCH_32BITS && (EMBTK_GCC_VERSION_4_8_X || EMBTK_GCC_VERSION_4_9_X)
		help
		 musl is a new general-purpose implementation of the C library.
		 It is lightweight, fast, simple, free, and aims to be correct
		 in the sense of standards-conformance and safety.

		 see http://www.musl-libc.org for more information about musl.

	config EMBTK_CLIB_UCLIBC
		bool "uClibc"
		help
		 uClibc is suitable for high memory constraints and MMU-less
		 embedded systems. But compatibility with glibc is not guaranted
		 and even between different uClibc versions.
		 see http://www.uclibc.org for more information about uClibc.
