+Description: Do not use -mavx flag
+ Note: Bug # 813438 report says:
+ "... bearing in mind that it's best to avoid
+ this option even on *amd64 because it normally limits the portability
+ of the resulting binaries (unless code relying on the extension is
+ carefully predicated on a CPUID test)?"
+ .
+ It needs to be discussed with upstream whether those CPUID tests are
+ done or not.
