	 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.

	config EMBTK_LLVM_ONLY_TOOLCHAIN
		bool "clang/llvm only (experimental)"
		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.

		 Userspace packages will be built with clang by default.

		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_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.
