Hey, you owe me beers for finding broken machines!
This machine was picked from a vague discussion on an internal chat.
The two requirements were that it would build, and boot in qemu.
If there's a better supported 32 bit machine then we should switch the
CI over. We don't want the Clang CI to be the only user and give the
false impression that someone out there is still booting upstream
kernels on it.
