I should warn you against including all of those -mno-xxx flags. This |
| 8 |
has been known to break the build process for packages like chromium, |
| 9 |
which always wants to build with SSE4 support and toggles it off at |
| 10 |
runtime. Passing -mno-sse4.1 causes a build failure as it tries to use |
| 11 |
macros that are not defined. |
