Running servers on PPC (or any big-endian machine) is not currently
supported because the ext3-patched on-disk data structures are not
handled in an endian-safe manner.  When we move to an ext4-based
ldiskfs this problem will be resolved.

That said, this compile problem is in the lfsck code (which is not
in upstream e2fsprogs) so it should probably be fixed at some point,
unless we finish the migration of lfsck into Lustre first.
