[petsc-dev] patch for batched config

[Barry Smith]

1)  If we do decide to adopt this usage in packages then it should go into the package.py class for GNUPackage not directly into the hypre one.

2)  If we do decide to adopt this usage then it should print to the screen in a "box" for each package it is doing this stuff, because it is likely fragile and 
needs to be told explicitly to the user and it being done and what its alternative is (should it break)

3) If we do decide to adopt this usage Satish will need to figure out how to run ALL the nightly builds using the --with-batch option so he can run all the nightly builds using the --with-batch option automatically so the -host option can get properly tested on a variety of systems.

  I think it is worth trying this but fear it is too fragile and will break often, hence we need proper testing before sticking into master.
