You missed another flag: USE="custom-cflags". You should really |
| 32 |
read USE flag descriptions (/usr/portage/use.{,local.}desc): |
| 33 |
|
| 34 |
custom-cflags - Build with user-specified CFLAGS (unsupported) |
| 35 |
www-client/firefox:custom-optimization - Fine-tune custom compiler |
| 36 |
optimizations (-Os, -O0, -O1, -O2, -O3) |
| 37 |
|
| 38 |
So custom-optimization will only get -O[0123s] option from your |
| 39 |
CFLAGS, if you need another options, use custom-cflags. If you need |
| 40 |
both (-O* and other options), set both USE flags (as can be seen |
| 41 |
from mozcoreconf-v4.eclass). |
