Hi,
Try disabling both '-mmx -sse' USE flags.
They are not regular optional USE-flags (only 'alsa kqemu sdl' are).
So two ways to go:
1.make a custom ebuild (/usr/local/portage/...) and disable 'mmx sse'.
2.use bashrc (custom CFLAGS) - check ML, Google etc.
2a.use 'paludis' :-)
What's your 'march' (in /etc/make.conf) ?
