OK. I've never scripted configure but I will give it a shot. From a brief
reading, it looks like I need to modify configure.ac.

You are correct that the argument applies to etags as well. I have never
used etags but my understanding was that it was used along with xref (which
I could be totally wrong about). I haven't used xref either. If emacs
doesn't need etags internally, then I don't mind an option to prevent its
build too.
