Deniz Bahadir 0e262c22a0 Fix / Workaround for issue #11224. (cont.)
* Extended script "boost_mpl_preprocess.py" to automatically call script
  "fix_boost_mpl_preprocess.py" prior to pre-processing and thereby
  automatically fix issue #11224.
* Extended script "fix_boost_mpl_preprocess.py" to just allow checking
  if the selected Boost source-directory requires fixing because of
  issue #11224.
* Adjusted the "README.txt" accordingly.
