This month, I did some more patches again.

Even found a toolchain patch for python310.
python3 still has some issues left around .pyc file reproducibility.

javadoc and xmvn are still problematic.
ghc has a regression fix pending (parallelism).
doxygen has some filesystem ordering issue.
and more esoteric things like octave, racket.

These big classes hide much of the remaining individual issues.
