CONFIG_EXTERNAL_KERNEL_TREE .config settings allows building the kernel
from an external tree directory. It currently only accept absolute path.
This patch is about allowing relative path. This is particularly convenient
if you have your openwrt and kernel sources hosted remotely, have several
persons working on the same sources, but possibly on different location on
their machine!
The code bellow check if the path is relative or absolute, and if relative
prepend it with openwrt TOPDIR path.
