- don't try to read the LIBS info from ROMIO's configure script if running

the script did not complete successfully
- ROMIO likes to default to using the system compiler if no compiler is
  specified.  This can lead to using a different compiler for ROMIO as
  for Open MPI, which is not always a good thing.  Reset the default to
  behave the same way Open MPI does.
