Changed unsafe-loop to unsafe-math optimizations.

Browse Source 
Details:
- Changed -funsafe-loop-optimizations (re-)introduced in 7690855 for
  make_defs.mk files' CRVECFLAGS to -funsafe-math-optimizations (to
  account for a miscommunication in issue #300). Thanks to Dave Love
  for this suggestion and Jeff Hammond for his feedback on the topic.
