Fix libltdl to always have all generated files up to date.

* Makefile.am (all-local): Depend on all generated files in
libltdl, namely...
(libltdl/aclocal.m4, libltdl/configure, libltdl/config-h.in):
...these.  List explicitly, including dependencies and
rebuilding rules, using...
(sub_aclocal_m4_deps, sub_configure_deps): ...these new
variables.
Report by Dan Lacher <Dan.Lacher@Sun.Com>.
