Robert, these are unrelated changes, so we'd prefer it if you submit
these as separate commits.  The problem with naming "python2" in the
script is that a lot of older machines don't have a "python2" (an old,
bad mistake by the Python community).  So until BuildSystem grows the
ability to use Python-3, those of us running systems where "python" is
python3 have to run

  python2 configure --options
