games-board/stockfish-17-r1 fails to compile on a AMD Phenom II CPU (I suspect it will fail in any x86 cpu that doesn't support ssse3). It's generating ssse3 instructions when the only active CPU_FLAGS_X86 are popcnt and sse (specifically, gdb is showing me that it's dying trying to execute the pabsd instruction). Reproducible: Always Portage 3.0.67 (python 3.12.9-final-0, default/linux/amd64/23.0/split-usr, gcc-14, glibc-2.40-r8, 5.4.97-gentoo x86_64)

Looks like more of https://github.com/official-stockfish/Stockfish/blob/6ceaca4c7b2cc1fa87617b1b9e83d38d8e880924/src/Makefile#L95 needs wiring up. (At least some of them, not checked all, end up controlling actual #ifdefs, not just used to pass -march to the compiler otherwise we could just make them all off.)
