CFLAGS=<set of flags you want> emerge --oneshot <package> |

ought to do the trick - it should override the make.conf setting. You |
| 15 |
can do the same with FEATURES. |

Aside from that, what you're really after is per-package CFLAGS (or |
| 19 |
more generally, per-package FEATURES) which is a long-standing portage |
| 20 |
feature request. You can do it via a bashrc script |
| 21 |
(in /etc/portage/bashrc) although it's not 100% - bashrc scripts are not |
| 22 |
sourced in all phases of emerge (in particular, fetch), although they |
| 23 |
are for the ones you're most likely to care about. |
