From 42c9321a15c2a98dd72cc09c7ef5900b5097c6eb Mon Sep 17 00:00:00 2001
From: Manuel Novoa III <mjn3@codepoet.org>
Date: Thu, 4 Aug 2005 03:49:25 +0000
Subject: Add BR2_CROSS_TOOLCHAIN_TARGET_UTILS to allow bundling of some useful
 debug apps with a deployed cross toolchain.  Should probably do ltrace as
 well... Also, add another compat symlink for cross gdb.
