The explanation for the strange thing in arch-cray-xt5-opt.py is: I
started off with a reconfigure.py file from a prior install by nersc
folks - so had some of this stuff in from there. [mpiexec.aprun is a
derivative of one of the scripts we have in PETSC_DIR/bin/mpiexec.*]
Looks like --with-mpiexec=/bin/false would also work on this machine.
currently mpiexec is checked by configure primarily for for 'make
test' stuff and 'check-mpi-shared' test.
We now have --with-batch=1 that generally works for machines where
things can't be run directly. Here - on cray - configure seem to work
directly - without batch - and without mpiexec.
Perhaps we can have configure - not abort if 'mpiexec' not found?
