Use X/Open LFS extensions for 64-bit support on directory iteration

This boils down to using readdir64(_r) and struct dirent64 where
available. I assumed these are available in the same platforms other
such extensions are already being used.

AIX uses the additional type DIR64 and opendir64/closedir64 to
manipulate it.
