How to unmask 3dnow and mmx use flags for amd64 system

Hello. I have a hp pavilion zv5000 with an AMD64 Athlon CPU. I quicly found that after typing in "emerge -pv [some package]", it spits out (-3dnow) and (-mmx).

The use flags seem to be masked.

Can anyone please help me find a way unmask them?

PS: I HAVE read a lot about portage and I know about putting use flags in make.conf. Portage just seems to think that my arch doesn't support 3dnow or mmx.

The 3dnow, mmx, mmx2, sse, sse2 flags are all hard masked ON on amd64 because all amd64s have those features.

Here is an exact quote when I try "emerge -pv xorg-x11"

Those are masked on the AMD64 profile because they're not optional. All AMD64 processors have those features, so to make the developers' lives a little easier they're always enabled where possible.
