From 56231056ea784f1cec6450f649b1adaed1f56366 Mon Sep 17 00:00:00 2001 From: Felix Fietkau 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__ becomes CONFIG_TARGET_, same for profiles.
