Yes, something is indeed broken. Please see the issue I linked for the details - emscripten uses llvm-ar, which does not provide a way to handle this case (in fact, it did, but it was removed...). We looked for a solution in the issue, but can't find a workaround except to write an implementation of ar ourselves, which no one seems interested to do, I suppose since the workaround tends to be simple. If you have new ideas on how to solve this, please comment in the issue, it would be great to have this fixed.
