Corresponding to what I said about the native syscalls, this should
eventually use 'old_timeval32' here.

and 'old_timespec32' here.

We could do those changes as a follow-up, but since you change that code
already, we could just as well do it now.

Then there is the question about the replacement. I don't see a need for
64-bit versions of time, gettimeofday or clock_getres, but we definitely want
a new clock_gettime. This probably has to wait until we have assigned a
syscall number (for the fallback implementation), just mentioning it now
so we keep it in mind.
