Hey @arichardson 

I had to just revert this patch with [2084a07](https://github.com/llvm/llvm-project/commit/2084a07087a55b55bb3c2a8aafbe1c4464fdf796) because it was breaking the buildbot as mentioned by @jplehr earlier along with our local builds.

In both cases, the error was the same : `unrecognized command-line option ‘-resource-dir=`

Let me or @jplehr know if we can assist you in anyway.
