Title: mpich2: Update to 3.1

This updates the `stable` and `devel` tracks to 3.1. In addition, now that the
default for the stable version of MPICH is to use shared libraries, there's no
need to have the `--enable-shared` option so it has been removed. The bug with
the clang library has also been fixed so that special code has also been
removed.
