When PETSc is installed into a prefix directory it no longer has a directory
component for $PETSC_ARCH. The test for PETSc MPI support didn't allow for
this case. The attached patch allows for this, but doesn't allow $PETSC_ARCH
to be unset.

P.S. The other workaround I found was to set PETSC_ARCH="/" ;)
