Subject: [PATCH] don't try to cross-compile sanitizer tests

this was a pre-existing latent bug, we just didn't have any CI builders exercising it.

fixes the following errors:
```
 ---- [ui] tests/ui/sanitize/new-llvm-pass-manager-thin-lto.rs#opt1 stdout ----

error in revision `opt1`: test compilation failed although it shouldn't!
