The attached patch fixes this but we then fail with

--no-stack-ir can be worked around by lowering the optimization from -O3
as it's triggered by
https://sources.debian.org/src/emscripten/3.1.66~dfsg-2/tools/link.py/?hl=434#L434
--no-growable-memory shouldn't be passed as we have ALLOW_MEMORY_GROWTH
and >= llvm-19 should even support it but emscripten depends on llvm-18
is that intentional (see the version check warning above)?
Cheers,
