There are CPUs like VIA C3 which don't have support for cmov and
i think gcc asumes that cmov is present if march is i686. Don't
know if this changed now.

I wouldn't like if i couldn't install Gentoo on my 800Mhz C3
machines anymore because something like -march=i686 is being used.

Maybe it's a radical point of view but i think generic i386 or
maybe i486 binaries are enough for a boot CD and stages. Almost
everyone will rebuild the stuff anyway. And i don't think there's
a huge speed loss until the binaries are rebuilt.
