* m4/libtool.m4 (AC_LIBTOOL_SETUP): Don't define the value for
ltmain unconditionally.
(_LT_PROG_LTMAIN): New macro to ensure that the
shell variable `ltmain' actually points at a suitable `ltmain.sh'.
(_AC_PROG_LIBTOOL): Require it.
(AC_LIBTOOL_CONFIG, _LT_AC_TAG_CONFIG): Invoke it.
* Makefile.am (libtool): ltmain.sh is in the build tree.
* libltdl/configure.ac: Ditto.
