From: Eric W. Biederman <ebiederm@xmission.com> - unquoted

By not using the enumeration in sysctl.h (or even understanding it)
the SN platform placed their arch specific xpc directory on top of
CTL_KERN and only because they didn't have 4 entries in their xpc
directory got lucky and didn't break glibc.

This is totally irresponsible.  So this patch entirely removes
sys_sysctl support from their sysctl code.  Hopefully they
don't have ascii name conflicts as well.

And now that they have no ABI numbers add them to the end
instead of the sysctl list instead of the head so nothing
else will be overridden.
