Make stops whenever a command it invokes fails, whether that command is
a compiler or a sub-make or whatever.

Don't do that. If you have to do that, then you have to manage the exit
yourself, because make takes your entire script and hands it to shell,
then make sits around waiting for the shell to be done. If you put a
loop into your command script, then the shell will execute it and
there's nothing make can do (or know) about whether it worked or not
until it's done.
If you have to do it in a list you should use something like:
for i in $(DIRS); do $(MAKE) -C $$i || exit 1; done
But the better way is to not use a loop at all (this latter method also
allows you to make full use of parallel or distributed builds should you
want to):
subdirs: $(DIRS)
$(DIRS):
$(MAKE) -C $@
.PHONY: subdirs $(DIRS)
