It depends on what you mean by "OK". It does work, as you mentioned,
and you're also correct that it won't play well with the -j
option... that is to say, it will not invoke the sub-makes in parallel;
only serially.
If you want to have it work well with -j you have to create a target for
each directory; maybe something like this:
PKGS.clean = $(PKGS:=.clean)
clean: $(PKGS.clean)
$(PKGS.clean):
$(MAKE) -C $(basename $@) clean
.PHONY: clean $(PKGS.clean)
