Bug#1069432: mpi4py: FTBFS on armhf: ld: cannot find -llmpe: No such file or directory

Followup-For: Bug #1069432

There have been ongoing issues with OpenMPI on 32-bit architectures,
partly related to drop of 32-bit support by pmix.

This bug is likely related to that i.e. not a bug in mpi4py itself.
