For testing this change, it may be easiest to just explicitly specify the triple or `-mx32`.

That doesn't help, unfortunately

The problem is that invoking `clang` on a Debian x32 defaults to `-m64` while it should default to `-mx32`. See my test run above.

I have not found the place yet in clang where to adjust that.
