The following patch for bsd.pkg.mk reduce work of patch making for LIBTOOL.
use USE_LIBTOOL_SYMLINK=yes instead of these patch.

	+if false; then
	 # Always use our own libtool.
	 LIBTOOL='$(top_builddir)/libtool'
	...
	 $libtool_flags --no-verify $ac_aux_dir/ltmain.sh $host \
	 || { echo "configure: error: libtool configure failed" 1>&2; exit 1; }
	+fi

pkg Makefile:

	USE_LIBTOOL=	yes
	USE_LIBTOOL_SYMLINK=yes
	GNU_CONFIGURE=	yes

Can I commit it?
