Absolutely. The build is being hosted on emscripten-forge (which uses version 3.1.45 on main)
1) recipe.yaml (https://github.com/emscripten-forge/recipes/blob/main/recipes/recipes_emscripten/llvm/recipe.yaml)
2) build.sh (https://github.com/emscripten-forge/recipes/blob/main/recipes/recipes_emscripten/llvm/build.sh)

I realize why the above patch is required .
