It would appear to me that make is the culprit (if the behaviour
change was not intentional, that is).

Here's the minimal makefile needed to reproduce it, and a transcript:

,--- detect.mk ---
build-stamp:
	echo $@

build-arch: build-stamp
`---

$ make --version | head -n1
GNU Make 3.81
$ make -f detect.mk -qn build-arch; echo $?
1

$ make --version | head -n1
GNU Make 4.0
$ make -f detect.mk -qn build-arch; echo $?
2


Thanks,
