Check for ar (libtool bug)

Hi,

libtool does not explicitly check for 'ar'.  If no other Autoconf
command checks for 'ar' before AC_PROG_LIBTOOL is processed, then
libtool uses AR=ar which fails when cross compiling.  Here is a
patch against libtool CVS together with a ChangeLog entry.

        * libtool.m4 (AC_LIBTOOL_SETUP): Check for ar.
