I used suffixes for this before, like this:
SUBDIRS := d1 d2 d3
TARGETS := clean all configure
ALLSUBDIRS := $(foreach t,$(TARGETS),$(addsuffix .$(t),$(SUBDIRS)))
clean: $(addsuffix .clean,$(SUBDIRS))
all: $(addsuffix .all,$(SUBDIRS))
configure: $(addsuffix .configure,$(SUBDIRS))
$(ALLSUBDIRS):
$(MAKE) -C $(patsubst .%,%,$(suffix $@)) $(basename $@)
or whatever. You can use $(eval ...) to make this much more clean. And
you'll need to make sure you declare all that stuff (certainly the
directories themselves) .PHONY.
Dependencies are more painful but again you can use loops and eval to
handle it.
