From 17c7b6c3fdc48301e50d22cc6138ede16bd1be24 Mon Sep 17 00:00:00 2001
From: nbd <nbd@3c298f89-4303-0410-b956-a3cf2f4a3e73>
Date: Thu, 6 Sep 2007 16:27:37 +0000
Subject: strip the kernel version suffix from target directories, except for
 brcm-2.4 (the -2.4 will be included in the board name here).
 CONFIG_LINUX_<ver>_<board> becomes CONFIG_TARGET_<board>, same for profiles.
