It looks like the WASI build script already sets WASI_SDK_PATH and WASI_SYSROOT https://github.com/Rust-for-CPython/cpython/blob/3.15-rust-in-cpython/Tools/wasm/wasi/__main__.py#L285-L286, perhaps it'd be better to just update the build.rs script to check if WASI_SYSROOT is set and add the argument there? Alternatively, you could set this environment variable in the WASI build script.
