Seeing the following on Fedora Rawhide with gcc 5.3.1:
checking size of Fortran type(test_mpi_handle)... configure: WARNING: Could
not determine size of type(test_mpi_handle)
configure: WARNING: See config.log for details
configure: error: Cannot continue

This is triggered by the use of hardening flags in Fedora builds - but the
problem seems to be that something is resetting FCFLAGS to empty during the
configure processes by the time this step is reached. I believe this is in
OMPI_FORTRAN_CHECK_USE_ONLY from
./openmpi-1.10.2rc1/config/ompi_fortran_check_use_only.m4. FCFLAGS gets set to:
FCFLAGS=$FCFLAGS_save
but nothing appears to be setting FCFLAGS_save.
