I tried to add "-lgfortran" into FLIBS (via $flibs_arch in the configure
script) but gfortran doesn't like that very much and croaks up an error.
However ifort is okay with this kind of redundancy (-lifcore -lifport)

I am guessing that we need more time to figure out how to teach nab
fortran. In the meantime, I am disabling pbsa in nab so that we can
still have a working Makefile_at building process.
