  Activate Emscripten 3.1.7 and source emsdk_env.sh.

  See node build.js --help for the upstream build options.

The app ships the unmodified upstream release binaries, not a private fork.
Rebuilding can produce different binary hashes because of compiler environment
and build timestamps; the exact distributed release hashes are in the app's
assets/engines/stockfish/provenance.json.
