clang/llvm: add initial configuration file for clang Add an LLVM backend and a clang toolchain variant to support building with llvm coming with popular Linux distributions. This has been tested with X86 boards: - quark_d2000_crb - quark_se_c1000_devboard/Arduino 101 Use: export ZEPHYR_TOOLCHAIN_VARIANT=clang Signed-off-by: Anas Nashif <anas.nashif@intel.com>

cmake: toolchain: llvm: Move the compiler assignment into 'compiler' Align 'clang' with gcc by having it also set CMAKE_C_COMPILER in the 'compiler' build script instead of the 'toolchain' build script. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>

cmake: toolchain: clang: Use 'find_program' and TOOLCHAIN_HOME Align 'clang' with 'gcc' by having it also use 'find_program' instead of 'set' to assign toolchain paths. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>

cmake: toolchain: Use ARCH instead of CONFIG_ARCH ARCH is available before CONFIG_ARCH, and is otherwise identical. So it is better to use ARCH than CONFIG_ARCH as this allows the code to be moved around more freely. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
