[PATCH] D25402: [Driver] Pass -lunwind when using libc++ + compiler-rt on Linux

[Joerg Sonnenberger via cfe-commits]

It's difficult to say whether if one change to certain driver functions affect some target or not. That's one reason why the test change is so important.

Looking at the latest version, I still don't understand why the change for Linux is needed. libc++ should provide a linker script now and that should include -lunwind as appropriate.
