Yeap, good idea. I could add `XFAIL` and modify runline like:

```
# RUN: link_fdata %s %t %t.patplt PREAGGPLT --synthetic --nmtool=llvm-nm
```

The differences would be :
- with `REQUIRES` we won't cross-run this x86 lit test on AArch64 (as I do currently in ` #137831`)
- with `XFAIL` + `llvm-nm` the test would be expected to fail on both architectures. But once your work is merged, it would unexpectedly pass, which would break the test and prompt us to update it

I'm happy to proceed with this as well.
