During a 3 stage build using CMake + Make , following a parallel build (`make -j 8 VERBOSE=1`)
I encountered the following error during the build of the `offload-tblgen` offload tool
```

```
After attempting to re-execute the build in serial `make -j 1 VERBOSE=1` to try and debug the errors 1 by 1 the build actually succeeded.
Could there be a missing dependency for the offload tools that can cause parallel build to fails if the dep is not resolved before the tool build?
