From 8a8d6d9e95d41e26b524080201869b2e41096b15 Mon Sep 17 00:00:00 2001
From: ryoon <ryoon>
Date: Mon, 15 Jul 2013 01:54:25 +0000
Subject: Add buildlink/builtin mechanism for devel/editline and
 devel/readline.

With this change, .include "../../devel/readline/buildlink3.mk" with
USE_GNU_READLINE=yes should be replaced with
.include "../../devel/readline/buildlink3.mk",
and .include "../../devel/readline/buildlink3.mk" without USE_GNU_READLINE
should be replaced .include "../../mk/readline.buildlink3.mk".

USE_GNU_READLINE is removed.
