Rust stable (nightly) wasm on osx

Basic setup taken from The Path to Rust on the Web

• Installing managed tools src src2
  • rustup target add wasm32-unknown-emscripten
  • brew install emscripten
  • brew install clang nodejs git - for llvm
• Running cargo build --target=wasm32-unknown-emscripten claims to work but no wasm or js are created
  • emcc -v complains about system llvm not having wasm target
