In order to work around an issue with flang based compilers,
avoid declaring bind(C) constants and use plain Fortran parameter
instead.
For example,
type(MPI_Comm), bind(C, name="ompi_f08_mpi_comm_world") OMPI_PROTECTED :: MPI_COMM_WORLD
is changed to
type(MPI_Comm), parameter :: MPI_COMM_WORLD = MPI_Comm(OMPI_MPI_COMM_WORLD)
Note that in order to preserve ABI compatibility, ompi/mpi/fortran/use-mpi-f08/constants.{c,h}
have been kept even if its symbols are no more referenced by Open MPI.

We previously needed to have empty targets because AM couldn't handle
having an AM_CONDITIONAL was targets in the "if" statement but not in the
"else". :-(
That now appears as an old automake bug that has been fixed,
so cleanup some Makefile.am
Thanks Jeff for the pointer.

(cherry picked from commit open-mpi/ompi@6e04b2a66a)
in order to solve an egg and the chicken problem, in which mpiext need mpi-f08-types.mod
and/but use-mpi-f08[-desc] needs mpiext, add an extra step
- build fortran 2008 modules only
- build fortran 2008 mpi extensions
- and then build fortran 2008 bindings
