Hello All

Please consider https://gerrit.zephyrproject.org/r/5355; it has been brought to our attention that the way we distribute kbuild and kconfig makes it look like it is Apache license, where it is actually original from the Linux kernel and thus covered by the GPL2.

This problem affects many other things we import/reuse into Zephyr, not making it necessarily a derivative work. This commit proposes a solution to it.

Thanks,
