Automatic regeneration of libtool

The libtool manual currently states:

~     This macro also sets the shell variable LIBTOOL_DEPS, that you can
~     use to automatically update the libtool script if it becomes
~     out-of-date.  In order to do that, add to your `configure.in':

~          LT_INIT
~          AC_SUBST(LIBTOOL_DEPS)

~     and, to `Makefile.in' or `Makefile.am':

~          LIBTOOL_DEPS = @LIBTOOL_DEPS@
~          libtool: $(LIBTOOL_DEPS)
~                  $(SHELL) ./config.status --recheck

~     If you are using GNU automake, you can omit the assignment, as
~     automake will take care of it.  You'll obviously have to create
~     some dependency on `libtool'.

Instead, I'd like to have LT_INIT perform the AC_SUBST([LIBTOOL_DEPS]), and
Automake generate the following rule when libtool is in use:

        $(LIBTOOL): $(top_builddir)/config.status $(LIBTOOL_DEPS)
                cd $(top_builddir) && $(SHELL) ./config.status $@

Does that seem like a sensible thing to want?

Cheers,
        Gary.
