I'd just leave the code as-is and just remove the ifdef cruft.  If
anyone is motivated enough to do real work on this area the callers
should simply be switched to readdir(3) and friends instead of
bikeshedding the current cruft.  I just don't want to put even more load
on Kyle how just wants to get xfsdump running on arm64..
