Subject: wasm: set stack size to 5MB again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recent Emscripten 3.1.27 reduces the stack size to 64KB,
which is way to small for Qt-based applications.

Restore the previous stack size (5 MB) by setting STACK_SIZE.
