This patch adds Kconfig options to select either GNU libgcc or LLVM compiler-rt. The 'rtlib' flag is provided in a config file, so this patch introduces 'clang_libgcc.cfg' and 'clang_compiler_rt.cfg' which enable appropriate library. The file is selected by concatenating the 'clang_' prefix with library name. Signed-off-by: Patryk Duda <pdk@semihalf.com>
