In theory you can get some cross compilers on Travis' trusty images. I
believe they have some docker based solution that might make it easier
to get cross compilation working for various (x86-based) distros.

We build a few variants but the data is hard to mine. We've been
experimenting with kernelci.org to aggregate result for kernel builds
from various places internally.

One problem would be where the information on failures should be sent?
