client-wasm.js test fails with clang >=22

[tstellar]

Bug Description

A recent llvm commit changed the visibility of the __stack_pointer symbol to make it global. This causes the client-wasm.js test to fail since __stack_pointer now appears on the list of exported symbols where it didn't before.

Reproducible By

Build undici with clang >= 22 (22 is not released yet, but can be currently found in the project's main branch).

Expected Behavior

Test passes.

The question is now, is there an option to hide the stackpointer or is it even relevant to have the stackpointer?
