The issue is not that the CFLAGS are unset when MPE's configure is invoked.  The issue is that we no longer have a "$(top_builddir)/bin/mpicc" wrapper script to use when building MPE, so a different code path is taken through MPE's configure.

Basically all of MPICH2 now except for MPE.  However, MPE probably won't quite look like most of the other build system conversions, since it's a totally separate layer that is intended to live above MPI rather than within/below it.  This is one reason that it was left alone at the time.
