[PATCH] D32366: Set "success" status correctly

I built lldb with XCode 8.3.3 on OX 10.12.6, using the latest from https://github.com/llvm-mirror/lldb.git, but I'm when I run the tests, I get nothing but errors. The errors are mostly related to being unable to find standard C++ headers like iostream, exception, cstdlib, chrono, etc.

I'm using the lldb.xcworkspace provided in the project. Is there something I need to configure?
