From bb701610aaa645644bfa046b30711fc5acb7c6c2 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 26 Jan 2013 13:44:47 -0500 Subject: buildsys: allow the toolchain to search its dirs for kernel headers Setting KERNEL_HEADERS up to the exact path all the time is a pita, especially when the toolchain is often times already configured to do the right thing. So if the user has set that to "", don't force any specific paths.
