I hope that this can be solved and that your Makefile restructuring
will be merged into master.

I prefer this cleaner solution you have just implemented too of course.

Is it possible with your current "make info" to get an info file
without git describe for a release like ELPA when made from within a
git repo and also for Emacs when building Emacs from a bzr-mirroring
git repo?

Thank you for this implementation. Since my patch discussed here is
now superseded by your branch I thought it would be cleaner to put my
comments to the sub-thread "Makefile restructuring" starting here:
