From 9f20b5f97fbd1106b1732fb1a36f094bd88172fd Mon Sep 17 00:00:00 2001
From: Ulf Samuelsson <ulf.samuelsson@atmel.com>
Date: Sun, 25 Jan 2009 21:48:33 +0000
Subject: Use new SHELL variable BUILDROOT_KERNEL_CONFIG_METHOD which will
 override selection between xconfig and menuconfig

make xconfig will, if it fails, or user does not save configuration
result in make menuconfig beeing tried

Fix several issues causing final part of linux to be regenerated
on each make.
