Oh, and if you want to automate this. I attached a ktest.pl config that
does it for you. I'll be pushing this config and others into a examples
directory come the next merge window.

Ktest is located in the Linux tree under tools/testing/ktest/

You can run a bunch of cross compiles by doing:

ktest.pl crosstests.conf
