Humm, that shouldn't happen, i.e. kernel developers don't have to update anything in tools/ as part of their normal kernel development workflows.
They can if they wish, but are not required, so the build failure was due to something else or a pre-existing bug where tools/ living stuff used things outside tools/.

Lemme try this on my Orangi PI zero...
