* libtoolize.m4sh (func_scan_files): Support projects that have
upgraded libtool, but still use an old autoconf.  When the libtool
macros are not copied (because of missing ACLOCAL_AMFLAGS and
AC_CONFIG_MACRO_DIR ), point them at the libtoolize master tree
for files to manually copy into acinclude.m4 or aclocal.m4.

 	for use by other parts of libltdl.  These are now static, so...
