This looks like a valid issue which I can reproduce locally on my Mantic system, but I am not sure the issue should be fixed in Ubuntu. Given that clang explicitly disabled support for -print-multiarch in [1], I doubt that's the right project to report this issue against.

I suggest reporting the issue against libsdl:
https:/ /github. com/libsdl- org/SDL/ issues
and see what they think about it.
