We've never worried about building with non-GNU make.  If you really want
to translate all of the Makefiles to old-style make syntax, it might be
possible, but it sure seems like a lot of make-work (pun intended).

Definitely; we still have at least one buildfarm animal without that.

mmm ... in principle yes, but you'll lose one heck of a lot of
functionality that's implemented in extension modules.  Possibly
that could be worked around by deciding which extensions you need
and statically binding them into the backend executable.  Again,
that's not a case we've worried about for the last twenty years
or so, so there's likely to be some pain there.
