The test requires not only the x86 target in LLVM, but also that ld.gold supports it, which will generally only be the case on x86 hosts. So I think the test needs something like `REQUIRES: x86_64-linux` (not sure if that's the right spelling...).

> @peter.smith thank you for pointing that out. I will be sure to update the documentation.

FYI this change also broke Rust LTO for the same reason (`.llvmbc` used for its own fat LTO equivalent). I expect that can be fixed by switching it to use `.llvm.lto`, but not sure if that will cause any other issues.
