-include $(pathsubst %.o=3D%.d,$(all-objs))

?  With a requiriment that all actually compiled objects be
listed in $(all-objs) somehow, either by adding them to one
of the common $(obj-y) or $(common-obj-m), or explicitly adding
them to $(all-objs) if it is used in some custom way.

Also, it can be done even funnier, something like this:

  subdirs =3D custom_subdir1 custom_subdir2
  subdirs :=3D $(sort $(subdirs) $(dirname $(objs)))
  -include *.d $(pathsubst %=3D%/*.d,$(dirs))

or just list all subdirs explicitly in $(subdirs).
There's nothing fancy in there really.

Thanks,
