 Well, _PATCH_DEPENDENCIES already does that:

# Order-only dependency
$$($(2)_TARGET_PATCH):  | $$(patsubst %,%-patch,$$($(2)_FINAL_PATCH_DEPENDENCIES))


 The problem identified by Gustavo doesn't happen in a normal build, it's only
when you do make source. That's because for source we use:

$(1)-all-source:        $(1)-source
$(1)-all-source:        $$(foreach
p,$$($(2)_FINAL_ALL_DEPENDENCIES),$$(p)-all-source)


 I have to think a bit more about possible solutions. But the good thing is that
it's less important: a normal build will still work without warning, and make
source will also still work and have all the packages, it just has a warning
that is not so nice. So if it doesn't get fixed for 2016.02 it's no disaster.
