Deterministic cross-compilation with Guix #22

I suppose this could be an entirely separate project. Though on the other hand, if someone were to build a full stack system including all the challenge-response bitcoin scripts, you'd probably want the whole thing to be deterministic. |

Different versions of GCC, as well as differences optimization settings and RISC-V target platform can result in different ELF files. See #16.
This seems like a great use case for Guix deterministic builds.
Some parts of Bitcoin Core's Guix build may be of use: https://github.com/bitcoin/bitcoin/tree/master/contrib/guix
Especially since Bitcoin Core already has some support for 32-bit RISC-V cross-compilation: https://github.com/bitcoin/bitcoin/tree/master/depends
Though the Guix build system only supports
riscv64-linux-gnu, not 32 bit:https://github.com/bitcoin/bitcoin/blob/master/contrib/guix/guix-build#L78-L80
But maybe it's not difficult to figure out how to make it work for a 32 bit unknown-elf target.
