I know which targets I want to build runtimes for, I don't want CMake to go on and try guessing which targets my compiler may or may not support. This needs https://reviews.llvm.org/D45604 but that change is ready to land so I might try and go with that approach.


I think that should work: Overriding the detection if `runtimes/` is known to produce the required dependencies. I don't see how this relies on https://reviews.llvm.org/D45604, but I might be missing something here.
