The new static linker in Xcode 15 does not emit the necessary symbols for file static thread local storage, causing this test to fail when used. The old static linker is still available as ld-classic in Xcode 15, but it has to be invoked specially, and the new static linker will be fixed at some point. I may try to add linker name and versioning information in lldb/packages/Python/lldbsuite/test/decorators.py like we do with the compiler / compiler_version, so it can be xfailed for known problematic static linker name / versions, but until I get that sorted I'm skipping this test to unblock the CI bots.
