It's only used when it needs to do something for which the CPU lacks
support so a call to an emulation is used instead of trying to generate
native code for it. Maybe you got lucky and ghc doesn't actually need it in
its C bits. Or maybe it'll explode only when there's a full moon in Scorpio
and Mars is ascendant. :/ (Well, when some rarely used operation happens to
need something that x86_64 needs help with. I don't think there are many of
those --- which means it's going to be an even rarer explosion.)
