[bug] Symengine with xeus-cpp-lite

[anutosh491]

Now that we're moving to emscripten 4-x. I see some errors with respect to the 3rd party libs notebook we have. Not a xeus-cpp but I'd guess, probably something wrong with how symengine is built against emscripten 4-x

1. This doesn't work

2. This works

Fixed through emscripten-forge/recipes#4126
