[PATCH] kbuild, LLVMLinux: Add better clang cross build support

From: Behan Webster Add cross target to CC if using clang. Also add custom gcc toolchain path for fallback gcc tools. COMPILER is previously set to "clang" if CC=clang was set from the make command line. So -target and -gcc-toolchain can be added to CC, since we already know that it is set.
