CFLAGS=<set of flags you want> emerge --oneshot <package>
ought to do the trick - it should override the make.conf setting. You
can do the same with FEATURES.
Aside from that, what you're really after is per-package CFLAGS (or
more generally, per-package FEATURES) which is a long-standing portage
feature request. You can do it via a bashrc script
(in /etc/portage/bashrc) although it's not 100% - bashrc scripts are not
sourced in all phases of emerge (in particular, fetch), although they
are for the ones you're most likely to care about.
