The mmx USE flag is not supported on the amd64 profile.  The processor
does support mmx instructions, but (I think) only when operating in
32-bit mode.  So it probably doesn't make sense to have an amd64
profile with the mmx/sse/3dnow use flags.  Presumably there are better
processor instructions for a true 64-bit multi-media application to
use...

If you really want to applications to use mmx/sse/3dnow for some
reason, you will need to remain in 32-bit mode with the x86 profile. 
Or I suppose you could use some kind of chroot/cross-compilation
environment...
