   This is needed for emscripten wasm builds

   Might be related: https://github.com/rust-bitcoin/rust-secp256k1/issues/283 since I was hitting the same error message that the rust wasm builds were hitting.

   It’s a nice discovery that the wasm failure is related to ar. Can you test #1088 instead? I think that’s the modern and recommended to solve the problem.

   edit: After thinking more about this, I actually don’t know why the current code fails. But I still think #1088 is the way to go, if it works.
