I think (info "(make)Prerequisite Types") provides just that. (And the
Features section at least doesn't explicitly say that this is unique for
GNU make.)
I.e. something like:
%.elc: %.el | bootstrap-emacs
cp $< $@
Apologies if I'm missing the point; I just wanted to point out this
rarely-used make feature.
