fix for libtool porting problem on AIX4 and AIX5 hosts

[Paul Eggert]

As Autoconf maintainer I received the following bug report about "configure":
http://mail.gnu.org/pipermail/bug-autoconf/2002-July/001693.html

This is actually a Libtool bug, that has been reported elsewhere,
e.g. for expat:
http://sourceforge.net/tracker/index.php?func=detail&aid=576396&group_id=10127&atid=110127

and for FreeType:
http://www.freetype.org/pipermail/devel/2002-March/003045.html

Here is a patch, relative to the current libtool branch-1-4 CVS
(libtool.m4 1.166.2.41):

        * libtool.m4 (_LT_AC_LTCONFIG_HACK): Fix typo: $AR was being
        passed $objdir, which it should be $output_objdir.  The former
        is a relative path, and we need an absolute path.  Original bug
        report and fix by Ian Brown for FreeType in
        <http://www.freetype.org/pipermail/devel/2002-March/003045.html>;
        bug forwarded to Autoconf mailing list by Fred L. Drake, Jr.
