Compilation compliant with MPI-2 standard

Description
Context
Compilation with key_mpp_mpi fails with some versions of mpi libraries
Analysis
mpi_iallreduce appeared with MPI-3.0 standard
Recommendation
It's not a bug, more a matter of choice. I may advice to add a logical to be able to switch back to MPI-2 compatibility, since MPI-3 is not so old. Or specify requirements somewhere. Or just mark this ticket as invalid.

I share your view that MPI 3.0 series is probably a little too recent for some people: https://www.open-mpi.org/software/ompi/versions/timeline.php
