Yes, that is my understanding. My plan was postponing such patches to
simplify stretch-backports. I'm not opposed to them in general, I just
didn't want to cause unnecessary work.

Yes, cmake is on the list above precisely due to sphinx. It also is a
key package, so it fits my description very well.

I certainly appreciate you putting effort in resolving these issues. I
also appreciate X-Debbugs-Cc (to record the bug numbers).

Debian unstable currently has almost 30000 source packages. Almost 14000
of them build architecture-dependent binary packages. (The others are
irrelevant to cross building). Around 7500 have cross-satisfiable
dependencies. I didn't work that much on satisfiability problems lately,
so this is only around 55%. Having you work here would be a boon. Of the
3900 packages that I tried building, 2900 do cross build. This is a much
higher ratio of almost 75%. Getting those 55% up would be awesome. If
you fix half of the sphinx users, we're 1% closer to perfection. :)
