llvm 20: NetBSD: lldb build failure

Trying to build lldb from the combined llvm-project-20.1.8.src tarball on NetBSD 11.99.5/x86_64 fails with:

```

Reproduce the LLVM 20.1.8 LLDB build on NetBSD, then inspect lldb/source/Plugins/Process/NetBSD/NativeProcessNetBSD.cpp at lines 306 and 493 and the Status constructor at lldb/include/lldb/Utility/Status.h:236. Compare the failing error handling with nearby code and confirm that the NetBSD LLDB build completes without these errors.
