Following the instructions in the README, everything seemed to be working fine until `./y.rs build`. ``` The MSVC toolchain is not yet supported by rustc_codegen_cranelift. Switch to the MinGW toolchain...
Fixes the issues found in https://github.com/bjorn3/rustc_codegen_cranelift/issues/1193. This still needs testing on CI. cc @EndilWayfare

When removing the tests requiring `rand` and adding a `Cargo.toml` to `src/libcore/tests`, running `cargo test` in that directory gives the following failures: ``` ---- checked_mul stdout ---- ---- checked_mul stderr...
