>Description:
- Fix a minor issue with FCFLAGS so more agressive optimizations are possible.
- This change follows the spirit of ports/98109 to elmer-mathlibs however no WITH_MPI knob is offered because it doesn't work until gcc41/gfortran are the default compilers.
- The gfortran port claims to be experimental so while a knob for OPTIMIZED_FLAGS is provided (and such a thing makes sense in this module) it is not encouraged.
