I have tried this with non-x86 builds and apart of a few problems all
looked fine. As it turns out I was using too old cross tools from
kernel.org [1]. Luckily Fengguang's kbuild robot did catch a bunch of
them (see the patches in this series).

Since Thomas was also surprised that only a bunch of them showed up,
I'll better give it another go with more recent compilers.

cheers,
daniel
