This was originally the way this worked before before https://reviews.llvm.org/D60882. In retrospect it seems inconsistent that `--allow-undefined` doesn't work for all symbols. See: https://groups.google.com/g/emscripten-discuss/c/HSRgQiIq1gI/m/Kt9oFWHiAwAJ I'm also planning a followup change which implement the full `--unresolved-symbols=..` flags supported by ELF linkers (both ld and ld.lld) since it seems more standard.
