Seems like we could drop this mess of a file entirely and just rely
on getdents64 from glibc. The raison d'etre of that file appears to
support 64 bit getdents before glibc really supported it, and I don't
think we'll have to support such old configurations anymore. I'll give
it a quick spin and see how that works out.
