Rebuilding rustc is probably overkill for your project. You likely just need to define a custom target and then use the -Zbuild-std option to build the standard library. Additionally, while don't know much about your target, rustc does support a few different riscv targets out of the box, it's worth running rustc --print target-list and seeing if any of them are appropriate.
