Motivation for this change

Spike is the RISC-V ISA simulator of the RISC-V project. It aids in developing RISC-V software.

Open Questions

I've pulled in cross compiled versions of hello and the RISC-V proxy kernel in the spike integration test. As far as I can see, this is the first integration test that relies on cross-compilation and I'm not sure that this is ok.
