The message is relatively self-explanatory: appchk,
being a static check, doesn't know what code paths
will be taken at runtime and so has no clue what
ioctls you're calling.

we inteded to have a matching dynamic checker which
could do that and related runtime work, but it's
never really been completed.

So I think you're compliant if you can affirm that
non-LSB ioctls are not called.  Or you could strace
the executable during a normal run to capture the
usage data.
