🤔 Expected Behavior

It should build without error

👟 Steps to reproduce

git clone --recursive -b feat/wasm https://github.com/thewh1teagle/aec-rs
cd aec-rs
brew install emscripten
rustup target add wasm32-unknown-emscripten
cargo build --release --target wasm32-unknown-emscripten
CC=emcc AR=emar wasm-pack build

🌍 Your environment

macos m1
wasm-pack version: wasm-pack 0.13.1
rustc version: rustc 1.82.0 (f6e511eec 2024-10-15)

Looks like it choose wasm32-unknown-uknown instead of wasm32-unknown-emscripten
