Roger that 
I'm also going to do some sleuthing on the docs.  Because the are validating mk file wasn't there on the last Build. Unless it contaminated something that maintainer clean didn't touch.  

I also need to audit if ghc or any of the boot libs invoke one of the lib gcc symbols.  Though I suspect not.

Indeed, this would be extremely helpful! In general it would be great if
someone could take a pass through the OS X build instructions; they seem
to be a bit dated.

Thanks!
