Tue Jul 9 19:14:16 PDT 2024

llvm-ci wrote:

LLVM Buildbot has detected a new failure on builder `sanitizer-ppc64be-linux` running on `ppc64be-sanitizer` while building `compiler-rt` at step 2 "annotate".

Full details are available at: https://lab.llvm.org/buildbot/#/builders/109/builds/783

Here is the relevant piece of the build log for the reference:
```
Step 2 (annotate) failure: 'python ../sanitizer_buildbot/sanitizers/zorg/buildbot/builders/sanitizers/buildbot_selector.py' (failure)
...

    Follow up to #98219

    This reverts commit
    [14f7450](https://github.com/llvm/llvm-project/commit/14f745074d05fb42f5c8a625c79bf557bb980ebb)

    Ensure that -pthread is explicitly linked when running the rtsan tests.

    Issue this fixes:
