This patch series aims at bringing the 5.x branch of OpenMPI to Guix.

First two patches are dependencies of OpenMPI 5.x.

Third patch adds a new package for OpenMPI 5.x, keeping OpenMPI 4.x as
the default version in package dependencies.

Fourth patch adds PMIx support, which is required for OpenMPI 5.x
support in SLURM.

These patches have been applied on top of commit
0663668507377a849317b0fff3d72f609c3139c2, all packages depending on
slurm and openmpi@5 have been successfully rebuilt.

Romain GARBAGE (4):
  gnu: Add openpmix.
  gnu: Add prrte.
  gnu: Add openmpi-5.
  gnu: slurm: Add PMIx support.

After thinking about it, the last two patches should be applied in the
reverse order so the when OpenMPI5 is present in the tree, SLURM already
has the PMIx support needed by OpenMPI5. 
If the need arises to submit a v2, I'll swap them at this occasion.

To be more precise, I rebuilt the packages that depend directly on slurm
and openmpi@5 (for the latter, there should be none for now).

Apart from the minor issues I reported, it LGTM!  Let’s see if qa.guix
can give it a try…
