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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
