mpi4py compilation error with openMPI 4.0

Archlinux has just bump openmpi to version 4.0. This version seems to remove some deprecated code, leading to this failure:

Regarding this issue https://bitbucket.org/mpi4py/mpi4py/issues/115/cannot-build-against-openmpi-400#comment-49251364 this should be fixed in mpi4py upstream.
