Tests failure when building on i686

[Wei-keng Liao]

Hi, Bruno

From file config.log generated on your i686 machine, it detected the size
of MPI_Offset being 4 bytes, which is the cause of the errors you are seeing.

This is related to an issue (bug) of OpenMPI recently discovered. See
https://github.com/open-mpi/ompi/issues/3195

My suggestion is to avoid using OpenMPI on 32-bit machines and
use MPICH instead.
