[cfe-dev] Link external libraries to Clang lit tests

[Murali, Sriram]

Thanks for the comments Eric. I noticed that the test-suite works off llvm-gcc. Is there a way to use clang instead?

We really don't want executable tests in that test suite. Things that _must_ execute should go in projects/test-suite from the main llvm project. If you think you must have a testcase to test something you should probably think of a different way to test it.
