| # Different build system distros set release optimization level to different |
| # things according to their local policy, eg, Fedora is -O2 and Ubuntu is -O3 |
| # here. Actually the build system's local policy is completely unrelated to |
| # our desire for cross-build release optimization policy for code built to run |
| # on a completely different target than the build system itself. |
| # |
| # Since this goes last on the compiler commandline we have to override it to a |
| # sane value for cross-build here. Notice some gcc versions enable broken |
| # optimizations with -O3. |
