Ok, I ran this locally. There are two problems: First, you had EMCC_FORCE_LIBS instead of EMCC_FORCE_STDLIBS in the environment options. Second, due to how asm.js works, the symbols also need to be exported, so this requires -s EXPORT_ALL=1 when building main. I honestly don't remember why that is needed, though - might be fixable, but this code is mostly deprecated as mentioned on the wiki.
