I'd definitely be interested in such a tool. Weather it be in form of a
make implementation or linter doesn't matter a whole lot to me as long
as the end goal of having a tool to help write portable makefile is
achieved.

Hmm, I was under the impression that `?=` was accepted into POSIX. But I
cannot find any mention of it in the posix manpage (man 1p make) so I
guess I was wrong.
What would be a posix replacement for `?=` ? I assume something like:
VAR = $$(if test -n "$$VAR"; then printf "%s" "$$VAR"; else printf
"fallback"; fi)
