[Mpi3-rma] GCC CAF

It's obviously a bit too late for MPI-3, but it might be a useful
exercise to make sure that MPI-3.0 RMA is sufficient for the GCC CAF
runtime (http://gcc.gnu.org/wiki/CoarrayLib).

It seems that it is though since they seem to support or attempt to
support ARMCI, which we know is compatible with MPI-2.2 RMA.

I know that GCC PGAS implementers are interested in MPI-3, if for no
other reason than neither GASNet nor ARMCI is an RPM in any Linux
distro of which I am aware.
