libtool/bootstrap
Gary V. Vaughan e46561b83e My thanks to Alexandre Duret-Lutz <adl@gnu.org> for the insight
required to write this changeset -- especially that ltmain.sh is
the same on any machine for a given release, which I hadn't
noticed for some bizarre reason: It turns out that generating
distributed files from configure causes no end of hassle, as
evidenced by the many patches I've generated over the last few
days to try and get the dist and distcheck make rules to work.
Instead of all that hair, we now simply generate our distributed
files (now including ltmain.sh) with make rules -- and since
automake creates make variables for all AC_SUBSTs, that is really
easy.  The code looks a lot more like automake and autoconf
Makefile.ams now, and doesn't have all the rough edges the earlier
hacky solution suffered from.  We still generate libtool from
config.status, but that is not a distributed file, and doesn't
break the golden rule.  Besides, there is way more going on there
than a bunch of substitutions:

* Makefile.am (edit): New common sed substitutions for files now
generated by make instead of config.status.
(CLEANFILES): Clean new tmp files.
(EXTRA_DIST): Add ltmain.sh.
(vcl-tmp): Reinstated.
(m4/ltversion.m4, config/ltmain.sh): New rules.  Generate from
here instead of config.status.
(libtoolize): Ditto.
(libtool): Call config.status to regenerate if necessary.
(dist-hook): Removed.
* config/ltmain.in: Moved here from top_srcdir.
* README-alpha: Update instructions to check AS_SHELL_SANITIZE is
up to date.
* bootstrap: Rewritten.  Generate m4/ltversion.m4 and
config/ltmain.sh because configure depends on them.
* configure.ac (AC_CONFIG_SRCDIR): Use libtoolize.in now that
ltmain.in has moved.
(AC_CONFIG_FILES): Don't generate distributed files,
config/ltmain.sh and libtoolize from config.status.  We have make
rules to do that now.

WARNING: them with `libtool.m4' as shipped with this distribution.
WARNING: After that, retry this bootstrap.
