This changes the default vectorization flag for Intel Fortran from -xCORE-AVX2 to -march=core-avx2. This change allows GEOS to run on both Intel and AMD EPYC chips at NAS without need for another build, see #240 for more details.

Closes #240

Moving to use -march=coreavx2 instead of xCORE-AVX2 with Intel Fortran?
