[config] Remove support for legacy environment variables#27381
Merged
Conversation
Remove support for legacy environment variables (`LLVM`, `BINARYEN`, `NODE`, `LLVM_ADD_VERSION`, and `CLANG_ADD_VERSION`) in `tools/config.py`. These have been generating warnings for over 5 years now (See emscripten-core#13922) to aid in transitioning to the modern `EM_*` prefixed variables (`EM_LLVM_ROOT`, `EM_BINARYEN_ROOT`, `EM_NODE_JS`, etc.).
