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
This is definitely a bug in GNU make 4.0 in handling -q. The docs are clear
on what the exit codes should be, and with -q make should exit with 1 if
something needs to be updated and no error was detected.
