           Summary: make buildworld clang failure
           Product: Base System
           Version: 10.0-RELEASE
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Only Me

With target source as 10.1 and completely cleaned again as 10.2 both yield the
same result, in the same place:
