  Log Message:
  -----------
  [libc++] Do not try creating llvm-lit when LIBCXX_INCLUDE_TESTS is OFF in the standalone build

Doing so doesn't work reliably, since it relies on LLVM_* implementation
detail variables being set. Furthermore, since we rely on the lit.site.cfg
being generated, running the tests requires LIBCXX_INCLUDE_TESTS=ON anyway.
