@jsquyres Could you please help me get this one moving forward?

Question: Is there any way (configure option?) to disable build/install of documentation, manual pages, etc. ?

the --disable-sphinx should stop attempting to generate docs

the --disable-sphinx should stop attempting to generate docswith release tarballs

Yes... but I still see manual pages being installed in make install. I'm just trying to figure out whether that step can be avoided to save time when building on an emulated architecture under Docker (something that we are not yet doing here, but I'm doing elsewhere with release tarballs to generate binary package for Python consumption).

Anyway, disabling man pages installations is not really a big deal right now.
I think everything is fine now and we should try to get this one merged ASAP.
