Also, isn't the -x86_64 redundant?  Also though I guess we don't have an mpi
variable MPI_NAME.

Also, your trick of using:

  for module in $(module avail 2>&1 | grep "^mpi/"); do

to find the available mpi modules needs a "-t" option for Lmod.  Fortunately
this also works with environment-modules:

 for module in $(module -t avail 2>&1 | grep "^mpi/"); do

Also, it doesn't seem to get all of the requires quite right.  For
scorep-openmpi I have:

Provides: libscorep_adapter_compiler_event.so.2()(64bit)(openmpi-x86_64)

but:

Requires: libscorep_adapter_compiler_event.so.2()(64bit)

is being emitted.  This appears to be coming from:

./fileattrs/libsymlink.attr:%__libsymlink_requires
%{_rpmconfigdir}/elfdeps --provides --soname-only

So it looks like we need to contend with that as well.

# cat fileattrs/libsymlink.attr
# Make libfoo.so symlinks require the soname-provide of the target library
%__libsymlink_requires          %{_rpmconfigdir}/elfdeps --provides --soname-only
%__libsymlink_magic             ^symbolic link to `.*lib.*\.so\..*'$
%__libsymlink_exclude_path      ^.*[[:digit:]]$


Perhaps with:

%global __libsymlink_exclude_path     ^%{_prefix}/lib(64)?/(openmpi|mpich)/.*$

in mpi packages.
