What you expected to happen

I expected a .wasm file to be generated.

Step-by-step reproduction instructions (by running brew install commands)

git clone [email protected]:ryanpcmcquen/basque.git
cd basque
brew install emscripten
emcc -s USE_SDL=2 -s USE_SDL_IMAGE=2 -s USE_SDL_MIXER=2 -s USE_SDL_TTF=2 -Wall -Wextra -std=c99 source/basque.c

A .wasm is generated with the same command using the upstream version of emsdk:
https://github.com/emscripten-core/emsdk

Here's the issue I logged against upstream originally:
https://github.com/emscripten-ports/SDL2_mixer/issues/2

Looks like we'll have to track the DEPS file described at https://github.com/emscripten-core/emscripten/blob/master/docs/packaging.md for LLVM. binaryen and emscripten tend to track pretty closely with releases, so we shouldn't track binaryen (or else this would be problematic, as we only ship tagged releases of binaryen in the formula, not any random revisions).

[alebcay]

I managed to reproduce your error via your reproduction instructions with the current version of emscripten that we ship; it seemed to build fine after the changes to emscripten in #63183. Hopefully that should do the trick.
