Gilles Gouaillardet 53b952dc2b oshmem: invoke the C PMPI_* subroutines instead of the MPI_* ones
when profiling is built.
This prevents oshmem subroutines from being wrapped twice by third
party tools (e.g. once in oshmem and once in MPI)
see discussion starting at http://www.open-mpi.org/community/lists/devel/2015/08/17842.php

Thanks to Bert Wesarg for bringing this to our attention
