Add pgi support for non-X86 systems.
I'm using PGI on Summit IBM power9 to test the GPU code. It is seems that fixing the configure is more appropriate on the main repo. Issues: MPIF90 doesn't propagate F90 pgfortran was recognized as gfortran.
My change should
- allow identifying the underling compiler of MPIF90 on non-X86 systems.
- pick up pgf90 and pgfortran on non-X86 systems
- all the arch=* rules moved to the end.
I have a version of autoconf older than the one generated the current configure Running install/refresh-configure.sh changes more than my intention. Could someone more experienced with autoconfig help me out? Just push to this merge request is fine.
