AFAIK GNU Make is available everywhere where Emacs can be built.
So while requiring GNU Make might occasionally be a hindrance because
the user has to first install GNU Make, it would not prevent
building Emacs.

For that reason, I'm not opposed to it.

Let's move this to emacs-devel to see if someone has a good reason to
oppose it.
