I'm trying this one more time, since the issue is still unresolved.

newfs(8) broke for big-endian systems since revision 204654. This change
made sectorsize variable int64_t, and now it cannot be passed to the ioctl
DIOCGSECTORSIZE.

The patch below (updated from the previous one) fixes it, please review and 
apply if correct.

Thanks,
JC.
