That sounds like it's one thing in https://lists.llvm.org/pipermail/llvm-dev/2020-October/146049.html I haven't extracted into a separate patch for submission yet: LLVM does not call `Triple::normalize` everywhere it should, and misinterprets x86_64-linux-gnux32 as x86_64-somethingelse when it's set as the default target because of it. For testing this change, it may be easiest to just explicitly specify the triple or `-mx32`.
