Fix compilation errors on macOS ``` clang++: error: unknown argument: '-fno-ipa-cp-clone' clang++: error: unknown argument: '-fno-ipa-cp-clone' make[1]: *** [bitboard.o] Error 1 ``` The flag is unsupported by Clang, which pretends to be GCC on macOS, so only passing -fno-ipa-cp-clone to real GCC fixes macOS builds. closes https://github.com/official-stockfish/Stockfish/pull/6698 No functional change
