disk space requirement for mpich2 during PETSc library compilation

[Barry Smith]

  Ben,

  This is partially our fault. We never run "make clean" on MPICH after the 
install so there are lots of .o and .a files lying around. I've updated
BuildSystem/config/packages/MPI.py to run make clean after the install.
