ok, but that's a separate change then
i think the relevant decision for out-of-tree is
if we want to keep
%.o: $(ARCH)/%.s
which means VPATH is needed, or if it's ok to have
.o files under the $(ARCH) dir, so the rules are just
%.o: %.s
%.o: %.sub
(of course setting $(OBJS) is more tricky then)
i think we can then do out-of-tree independently from
the subarch changes.
