I think I would prefer to keep the 1:1 mapping between virtual target
name and real target name, and only have aliases when it makes sense.
I.e:

$(1)-rsync:	$$($(2)_TARGET_RSYNC)

# Possibly some comment here to explain what's going on
$(1)-extract:	$(1)-rsync
$(1)-patch:	$(1)-rsync

Otherwise, I'm fine with fixing this problem using this approach, looks
good to me.
