Details of the problem

Configured with --with-mpi-moduledir=/usr/lib64/gfortran/modules/openmpi, install fails with:

/usr/bin/make  install-exec-hook
make[4]: Entering directory '/builddir/build/BUILD/openmpi-5.0.5-build/openmpi-5.0.5/ompi/mpi/fortran/use-mpi'
/usr/bin/install -p mpi_types.mod /builddir/build/BUILD/openmpi-5.0.5-build/BUILDROOT/usr/lib64/gfortran/modules/openmpi
/usr/bin/install: cannot create regular file '/builddir/build/BUILD/openmpi-5.0.5-build/BUILDROOT/usr/lib64/gfortran/modules/openmpi': No such file or directory
make[4]: *** [Makefile:1707: install-exec-hook] Error 1

I would expect it to be able to create any needed sub-directories.
