autobuild hooks

I haven't yet used autobuild, but I know several projects, including
coreutils, find it useful.

http://josefsson.org/autobuild/

So I'm checking in this, to match this morning's new gnulib module.
You'll need to run either './bootstrap' or 'gnulib-tool --update'.

        Enable autobuild usage.
        * ltdl/m4/gnulib-cache.m4: Augment with 'gnulib-tool --import
        autobuild'.
        * configure.ac (AB_INIT): Output autobuild information.

Don't work too hard, make some time for fun as well!
