Currently sysctl_check_table will complain if a strategy routine
is missing when we have sys_sysctl compiled out, or a proc_handler
is missing when we have procfs compiled out. At least some
of the custom handlers actually expand to NULL when this is the
case so the warning is actually a problem.

So don't worry about missing strategy routines, or missing proc_handler
routines when they will never be called.
