So you want to execute $(MAKE) for each dir.
There are several ways to do so:
1) Using the shell
subdirs:
for D in $(SUBDIRS); do make -C $D; done
2) Using the builtin shell
subdirs:
$(foreach D, $(SUBDIRS), $(shell $(MAKE) -C $D))
3) Using dependencies
subdirs: $(SUBDIRS)
$(SUBDIRS):
$(MAKE) -C $@
This is all from memory and un-tested..
