What does LIBTOOL_DEPS contains? It's unclear to me when
libtool needs to be rebuilt and how me managed without such rule
so far. Except in the Libtool package itself, I believe
libtool.m4 does change when ltmain.sh changes, doesn't it? So
libtool would get updated as a side-effect of
rebuilding/rerunning configure.
I have a small problem with using $(LIBTOOL) as a target of a rule,
because many people have overwritten LIBTOOL in they Makefile.am
to insert a --tag option.
Also such a rule would be triggered only if something depends on
$(LIBTOOL), which I believe is not the case (same problem with
--tag here). Is such a dependency desirable? IOW should every
libtool target be recompiled whenever config.status changes?
