Support for fat64 is still largely experimental, and the -fat64 flag is intentionally undocumented. I suggest omitting it from llvm for now, in case we decide the implementation needs to change before we roll the feature out ourselves. Otherwise, you run the risk of forking the Mach-O file format, which would be ... unfortunate.
