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")
