Fixes for more issues found by Dries Kimpe:

- We had a bad conditional choice, such that asking for pvfs2 would
    result in pvfs trying to build as well, which was going to fail.
  - We didn't try to link in the libray for PVFS2's adio component.
  - We were clobbering romio_flags, so it was impossible to pass
    flags to romio (like the selection of filesystems)
