How are out-of-tree builds supposed to work? I had added `-DLLVM_ENABLE_RUNTIMES="flang-rt"` to our existing flang builds (which leverage pre-built llvm, clang & mlir), and noticed that nothing related to `flang_rt` gets built. Upon closer inspection, this is unsurprising, because the config step ignored that variable:
```
CMake Warning:
-- Generating done (1.7s)
  Manually-specified variables were not used by the project:

    LLVM_ENABLE_RUNTIMES
```
