better compiler options for Portland pgfortran
revert pgfortan to pgf90 (although in principle pgfortan is the standard name these days, but it seems to break BuildBot)
got rid of compiler option -Mipa=fast,inline for pgf90 because it creates problems with some older versions of that compiler
changed pgf90 back to pgfortran, since the problem detected by BuildBot was not coming from that
