I think this does what you want - things should depend on 
"gllib/stamp-make" to make sure that it gets rebuilt.

---------------------------------------------------

gllib/Makefile: config.status
        mkdir -p $(dir $@)
        sh config.status $@ depfiles

gllib/stamp-make: gllib/Makefile
        cd $(dir $@) && $(MAKE) CFLAGS="$(SUBDIR_CFLAGS)"
        touch $@

---------------------------------------------------

Should gllib/Makefile also depends on depfiles?
