[compiler-rt] r244634 - [cmake] Handle external source for lld and libcxx

[Chris Bieneman via llvm-commits]

This breaks standalone compiler-rt builds because it adds a dependency on AddLLVM.cmake which isn’t relied on anywhere else.

We should consider doing this differently since the plans for compiler-rt's CMake rely on standalone builds working.
