From fd1b50c5ff9c288040abf5e78815151327d32e0e Mon Sep 17 00:00:00 2001
From: Ilya Yanok <yanok@emcraft.com>
Date: Mon, 20 Jun 2011 12:45:37 +0000
Subject: config.mk: move LDSCRIPT processing to the top-level Makefile
Upstream-Status: Accepted
LDSCRIPT is used only from the top-level Makefile and only when the
system is configured so we can move LDSCRIPT and CONFIG_SYS_LDSCRIPT
related logic into the top level Makefile and under configured condition
to avoid errors when building tools from unconfigured tree.
