    Merge commit bfb276e55c76 from upstream OpenZFS (by Jessica Clarke)
    
      Once upon a time, 32-bit PowerPC did indeed have a 32-bit time_t, but
      FreeBSD 12.0 switched to a 64-bit time_t for PowerPC as an ABI break,
      which predates the addition of FreeBSD support to OpenZFS. Moreover,
      64-bit PowerPC has existed since FreeBSD 9.0, where __powerpc__ is also
      defined (alongside __powerpc64__ to disambiguate), which has always had
      a 64-bit time_t. This code has therefore always been wrong for all
      PowerPC variants. Fix this by limiting the 32-bit case to just i386,
      which is the only architecture in FreeBSD to have a 32-bit time_t and
      not have broken ABI, due to its special legacy compatibility status.
