Yes, it is possible, but it requires a full, single threaded bootstrap
build, which takes about an hour for me.

The same ldefs-boot (generated from master) works on emacs-25 head, and
master. It fails on emacs24 head because of inline.el and emacs-24.3
because of nadvice.

Of course this is going backward in time, not forward, so the number of
required autoloads could just be getting bigger. But given that the
number of quite small, that seems unlikely.
