I think he was implying something like this:

MODULE_LIST:=one two three

.PHONY: all
        @echo $(MODULE_LIST)

define clean_module
.PHONY: clean_$(1)
        @echo "Clean: $(1)"
CLEAN_EXTRA+= clean_$(1)

$(foreach MODULE,$(MODULE_LIST),$(eval $(call clean_module,$(MODULE))))

.PHONY: clean
clean: $(CLEAN_EXTRA)
        @echo "Clean: main"
