Well, then... let's build 32-bit x86 with -O0. Or add a few sleep()s
strategically in glibc. That'll teach them.

Seriously, if there is a huge non-SSE2 (or, heck, non-SSE - that brings
back in Athlon-XP/MP and P3) userbase, that I can understand. But saying
'let's not try and make it better when we can do so with trivial effort - let's
leave it slow/make it slower'... that's just silly.
