No more details at this hour, that much just came up in a short code
inspection looking for EXTRA_PYTHON and what it controlled.

It's OK.  We are all feeling the stress!  I'm required to be at work
until Thursday (to review and guide the last things at our end,
thankfully all much less dramatic) and I'm already counting down the
days.

Thanks you so much for all your hard work and I look forward to helping
you land this in a couple of weeks after a good rest for us both.

Beyond the fiddly stuff, the next important step (after landing this)
will be that python3 build I think, and doing the same build and
config.h comparison with that.  We probably need an autobuild job in
that mode.

Then just the long slog though the remaining python3 conversion.  We
were all too busy today so I didn't grab the feedback from Joe. 
Monday! This time really :-)

Once we get python3 working, I would vote we ditch python2 ASAP (beyond
waf).  A hard sell (backporters needing to use eg raskpace or software
collections python repos for Samba on older systems) but worth it I
feel.
