[libcxxabi] r322768 - Fix standalone test-suite run.

[Eric Fiselier via cfe-commits]

New Revision: 322768

URL: http://llvm.org/viewvc/llvm-project?rev=322768&view=rev
Log:
Fix standalone test-suite run.

This patch updates libc++abi's HandleOutOfTreeLLVM.cmake to match
libc++'s -- and more importantly, to fix a bug where llvm-lit wasn't
found/created when libc++abi was built out-of-tree. This prevented
the test suite from running.
