MC/Mach-O: On second thought, use a custom hook for enabling aggressive
IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on
enough cases for x86-32 that I would rather wait a bit on it.
- In practice, we will want to change this eventually because it only means we
generate less relocations (it also eliminates the need for the horrible
'.set' hack that Darwin requires in some places).
