openmpi uses deprecated fortran wrappers / should use mpifort

[platipodium (Carsten Lemmen)]

mpifort is a new name for the Fortran wrapper compiler that debuted in Open MPI v1.7.

It supports compiling all versions of Fortran, and utilizing all MPI Fortran interfaces (mpif.h, use mpi, and use mpi_f08). There is no need to distinguish between "Fortran 77" (which hasn't existed for 30+ years) or "Fortran 90" -- just use mpifort to compile all your Fortran MPI applications and don't worry about what dialect it is, nor which MPI Fortran interface it uses.

Other MPI implementations will also soon support a wrapper compiler named mpifort, so hopefully we can move the whole world to this simpler wrapper compiler name, and elminiate the use of mpif77 and mpif90.

Specifically: mpif77 and mpif90 are deprecated as of Open MPI v1.7. Although mpif77 and mpif90 still exist in Open MPI v1.7 for legacy reasons, they will likely be removed in some (undetermined) future release. It is in your interest to convert to mpifort now."

Classified as defect, as 3rd party software relies on existence of mpifort wrapper with Open MPI v1.7 and better.

I guess when mpich implements this, we can easily change things at once in the mpi port group. I don't know what else to do besides wait.

mpifort was added generally in r122477.
