It is safe. At least until you do not hit some compiler bug. But bad side-effect is that with -march compiler uses non-compatible optimizations. This code may not work anymore on any other processor. This is what differs it from -mcpu flag. If you look into configure scripts of MySQL, you see -march commented out because same reason.
