For bootstrapping a kernel, I had trouble with cross compiling. My kernel doesn't yet support a libc hosted environment, so I use a i686-pc-elf gcc target with -ffreestanding. rustc works niceley if your target environment is similar enough to your dev environment, or if you are developing for android for which there's an sdk and rustc port already. I initially tripped up on this because i'm developing on osx currently, but targetting gnu. I just need the rustc equivalent of -ffreestanding. Alternatively I'll have to wait until I've got a proper i686-myos gcc and libc port.
