=> the delayed-ask feature is incompatible with
DHCPv4-over-DHCPv6 so we should make impossible
to compile both features (i.e., required updates in docs
and configure).

Note the change must be done to configure.ac-base
(vs configure.ac).

The code itself is OK but not configure*, RELNOTES and
dhcpd.conf.5.
