With ASan testing enabled on SPARC as per PR #<!-- -->107405, the
```
  AddressSanitizer-sparc-linux-dynamic :: TestCases/Linux/preinstalled_signal.cpp
```
test `FAIL`s on Linux/sparc64.  See Issue #<!-- -->109573 for all the details, but the core is that `syscall(__NR_rt_sigaction)` cannot be used because it takes an additional argument that isn't accessible outside of `libc`, while switching to `sigaction` instead changes the order of `AsanInitInternal` and `Init`, breaking the test.

Therefore this patch `XFAIL`s the test.

Tested on `sparc64-unknown-linux-gnu` and `x86_64-pc-linux-gnu`.
