There is always the bashrc to set CFLAGS on a per-package basis.

I think the main issue would be with hardened, where mmx is already a problem 
on some packages, but I think this can be solved.
For any package where enabling mmx create stability problem, it's likely the 
support should be removed altogether anyway, as the flag is enabled for the 
majority of users already (the same goes for the other flags).
