[patch] libtoolize --acdir --ltdir

[Rusty Ballinger]

Hey, this is a patch to add --acdir and --ltdir arguments to libtoolize;
I mistakenly sent it to the automake list instead of libtool-patches.

Here was my original note about the patch:

    It's nice that autoconf's --macrodir and automake's --amdir let you
    specify alternate directories to load files from.  Unfortunately, when
    automake calls libtoolize, it appears that there's no way for it to
    tell libtoolize to use a different pkgdatadir or aclocaldir.

    One approach would be to add --acdir and --ltdir command-line arguments
    to both libtoolize and automake, and make automake pass these on to
    libtoolize.

Here's the portion of the patch which applied to libtoolize.  Note that the
documentation changes could be horribly wrong; I just guessed at what to do
by looking at another patch on the mailing list.
