You can't just forget about FILE_OFFSET_BITS=64.  On the other hand,
it's fairly simple to simply pass O_LARGE to open(), and then set up a
situation where you only try to call lseek64() if you need to seek to an
offset larger than 32 bits.  O_LARGE should be ignored on non-LFS
systems, and if lseek64 returns ENOSYS, you know you're on a non-LFS
system, and you can simply truncate the restore of the large file at
that point, with a warning message.
