Let's not make it worse for now. All the numbers since the
introduction of the time64 syscalls are offset by exactly 120
on alpha, and I'd prefer to keep it that way for the moment.
I still hope to eventually finish the conversion of all architectures
to a single syscall.tbl for numbers >400, and if that happens before
the end of alpha, a different ordering would just be extra pain.
