I'm toying with building a little OS using the Linux kernel and an all-Go userspace, and one of the goals is to make the entire system as easy to cross-compile (both host OS and host/guest CPU arch) as possible. Linux being non-trivial to compile (let alone cross-compile) has been so far quite a nuissance, so I'll definitely be having a closer look at this.
