What: Change the mpicc/mpicxx/mpif77/mpif90 from being binaries to being
Why: Our build environment assumes that wrapper compilers will use the same
binary format that the Open MPI libraries do. In cross-compile environment,
the MPI wrapper compilers will run on the front-end and need to run on the
front-end, and not the back-end. Jeff has suggested this as the simplest
way to build back-end libraries, and front-end wrapper-compilers.
When: within the next several weeks (for the 1.3 release)
