  MFC r202964:
  On FreeBSD, time_t is 64-bit for all platforms except i386 and powerpc,
  where the type is 32-bit.  ZFS can handle 64-bit timestamp internally
  but zfs_setattr() would check if the time value can fit, we change the
  checking macros to match 64-bit timestamp if the platform supports it.
  This change has some downsides like, while you can import zfs on 32-bit
  platforms, the timestamp would overflow if they are out of the range.
  This fixes the Y2.038K issue on platforms using 64-bit timestamps.
