Adrian Ratiu 7fd9fd46a4 tools: Fix unavoidable GCC call in Clang builds ... In ChromeOS and Gentoo we catch any unwanted mixed Clang/LLVM and GCC/binutils usage via toolchain wrappers which fail builds. This has revealed that GCC is called unconditionally in Clang configured builds to populate GCC_TOOLCHAIN_DIR. Allow the user to override CLANG_CROSS_FLAGS to avoid the GCC call - in our case we set the var directly in the ebuild recipe. In theory Clang could be able to autodetect these settings so this logic could be removed entirely, but in practice as the commit cebdb73745 ("tools: Help cross-building with clang") mentions, this does not always work, so giving distributions more control to specify their flags & sysroot is beneficial.
