Fix bugs in both r27817 and r27821. For some reason, I removed the conditional

around OMPI_SETUP_MPI_FORTRAN in r27817 when removing the OPAL hacks for the
no-Fortran case.  Then r27821 worked around a build issue caused by
r27817 in a sub-optimal way.

This commit was SVN r27826.

The following SVN revision numbers were found above:
  r27817 --> open-mpi/ompi@fc3df11e08
  r27821 --> open-mpi/ompi@0ede5be003
