This results in numerous compiler errors:

It is using functions that were only added in Linux 4.18 so I think it
should be reverted from the 4.4, 4.9, and 4.14 stable branches.

Sigh... I didn't think of adding cross compilation to the tools dir...

Thanks for this, now reverted for those branches.
