From 5369f55021feb27a1481267e7afefe14128d669f Mon Sep 17 00:00:00 2001
From: Michal Marek <mmarek@suse.cz>
Date: Sat, 7 Jul 2012 23:04:40 +0200
Subject: [PATCH] kbuild: Print errors to stderr
... at least in the top-level Makefile and scripts/link-vmlinux.sh.
There are some more instances of the 'echo <error>; exit 1' pattern in
some arch Makefiles and kconfig.
