Originally we were not using `OBJTREE` in the `kernel` crate, but we
did pass it anyway, so conceptually it could have been there. So I am
not sure if it counts as a fix for that commit, but it shouldn't hurt
even if backported.

Regarding `include_dirs`, it started in `kernel` before being in
mainline because we included the bindings there (i.e. there was not
`bindings` crate), but it should have been probably moved when it was
split. Nowadays, I guess we still need it for
`generated_arch_static_branch_asm.rs`, or is it something else that
needs it? I assume it shouldn't hurt, in any case, so it looks OK.

Cheers,
Miguel
