[PATCH] D61016: [lit][tests]Add libc++ to link XRay test cases if libc++ is used to build CLANG

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast added a comment.

The test updates make sense given the current Clang driver behaviour; however, I think there is a question as to whether the Clang driver should be updated to add `-lc++`, etc. as necessary when it "automatically" links in `compiler-rt` libraries with such dependencies.
