Makefile: Do not use GCC specific options with LLVM/clang
Building with LLVM/clang (`COMPILER_LLVM_CLANG=y`), Debian clang version 11.0.1-2 fails due to unknown warning options. error: unknown warning option '-Wlogical-op'; did you mean '-Wlong-long'? [-Werror,-Wunknown-warning-option] error: unknown warning option '-Wduplicated-cond' [-Werror,-Wunknown-warning-option] As these are GCC specific, only add them, when building with GCC (and not scan-build). Fixes: 04e0712f46 ("Treewide: Add some gcc's warning options") Change-Id: I6190c1f3df97fb0be51f8dab7e1f5f2a033f5d86 Signed-off-by: Paul Menzel <pmenzel@molgen.mpg.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/50771 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
