Changes v3 -> v4:
* Use LINUX_MAKE_FLAGS instead of directly specifying CROSS_COMPILE (suggested by Yann)

Changes v2 -> v3:
* Add info about supported Linux version in Config.in (suggested by Baruch)

Changes v1 -> v2:
* Adapt to new linux-tools infra, which is moved to package/ directory (suggested by Yann)
