Following instructions from the readme and emscripten, I get this error

Testing config sanity. If this fails, try 'make help' ...

This is probably due to latest emscripten being incompatible with this build, going to try to find either a different stockfish js or the correct version of emscripten to use.

Thanks for reporting. I am not actively maintaining this repository, because it is superceded by https://github.com/niklasf/stockfish.wasm in modern browsers, but I will merge proposed fixes.
