Most upstreams that hardcode SSE2 also do not distinguish between various
i*86. They just check for x86 and use SSE2 instructions there, or even just
use SSE2 instructions unconditionally (making them entirely x86/x86_64-
only). So --target i586 isn't going to do anything for them. Rust seems to
be the one case where it would help.
