libtool/bootstrap.conf
Gary V. Vaughan 0024c50ba3 bootstrap: remove support for -r' and reconf_dirs'. 
With all those extra demo directories out of the way, we can
revert to a more canonical bootstrap process, and jettison the
cruft that was only there to work around the pain of
needing to autoreconf 11 directories.  Bootstrap is now an order
of magnitude faster.
* bootstrap.conf (require_ltdl_dir): New function. Factored out
of `libtool_build_prerequisites'.
(libtool_build_prerequisites): Adjust.
(func_reconfigure): Use `require_ltdl_dir' to determine the name
of the other directory we need to autoreconf during bootstrap.
(libtool_options_prep, libtool_parse_options)
(libtool_validate_options): Remove.
