This breaks some of my builds.  I believe this won't work in general unless you make sure that the object file is built before `FortranRuntime` target tries to build, i.e. there has to be a target dependency in this CMake file.

I think you can try to reproduce it by deleting the module object file and running `make FortranRuntime` - it will fail with something like:
```
No rule to make target `tools/flang/tools/f18/iso_fortran_env_impl.o', needed by `lib/libFortranRuntime.a'.  Stop.
```
