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

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