            Bug ID: 228063
           Summary: Ignore weak external symbols in clang coverage builds
                    using check-for-weak-vtables-and-externals

           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Tools / Tests

Ignore weak external symbols in clang coverage builds using check-for-weak-vtables-and-externals.

It turns out that -exported_symbol and -unexported_symbol can't be used together when linking:

    ld: can't use -unexported_symbol and -exported_symbol
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

So go back to the solution from Bug 226562 (effectively reverting the change for Bug 226684).
