If

  cd bfd/doc
  while make clean && make -j8 all; do :; done

without the patch exposes the bug, then it should verify the bug is
fixed with the patch.  You might have to rm more files for cleaning
and/or add 'info' or so to the 'all' target, but the above should do
dozens or tries per minute so give a fairly reliable answer after an
hour or so.

Thanks,
Ralf
