    Hi!

Maybe it's because today is Friday the 13th but Clang 15 of https://apt.llvm.org/ started being unusable today for Ubuntu focal/20.04 with `-fsanitize=address`, failing to link even tiniest programs with this link error:
```
/usr/bin/ld: cannot find /usr/lib/llvm-15/lib/clang/15.0.7/lib/linux/libclang_rt.asan_static-x86_64.a: No such file or directory
/usr/bin/ld: cannot find /usr/lib/llvm-15/lib/clang/15.0.7/lib/linux/libclang_rt.asan-x86_64.a: No such file or directory
```
The full log can be seen at https://github.com/libexpat/libexpat/actions/runs/3907902403/jobs/6687221899#step:6:108 and I'm attaching a copy of the full log here: [clang-15-error.txt](https://github.com/llvm/llvm-project/files/10412860/clang-15-error.txt).

Any chance this can be fixed? I'm expecting this affects a lot more projects than just libexpat.

Let me use the occasion to thank you for all the work you do on Clang and LLVM: in particular Clang's sanitizers have been invaluable again and again and to have clang-format is also great. Thank you!

Best, Sebastian
