Other architectures (frv, xtensa, score) currently fail to build for other reasons,
so I don't really know if the above are the only ones affected.

I think the best solution would be to add them to kernel/sys_ni.c so we can
assign syscall numbers for all architectures regardless of whether they use it
or not (most of them will never use these AFAICT).

Urg, sorry about the breakage.  I'll see if I can reproduce it and get a
patch out later today that does this.
