[PATCH v3 0/1] Makefiles: GNU make 4.4 fixes

A now much-smaller re-roll of a potential for-v2.39.0 fix for GNU make 4.4 compatibility.

Junio: Sorry about the overlapping submission, at the time I didn't
see Paul's in the "What's Cooking", and thought it hadn't been picked
up at all (maybe I just forgot to look at the actual branches).

This v3 is just the "MAKEFLAGS" patch. I agree with your [2] that we might want to leave this post-release, i.e. it'll just be (a lot) more verbose, but does it break anything? Probably not.

On the other hand the fix here is trivial, and literally just the exact solution to this compatibility problem suggested by GNU make's "NEWS" file, and nothing else. So merging this before the release should be low-risk...
