New description:

 Currently to build Kea, all modules need to be build, and all dependencies
 must be present. This is problematic. It was agreed on a Kea 1.0 alpha
 planning meeting that BIND10 must be modular.

 I think at the very minimum we need the following switches:
 --enable-dns
 --enable-dhcp

 It would be better if we had the following:
 --enable-dns-auth
 --enable-dns-resolver
 --enable-dhcp4
 --enable-dhcp6
 --enable-dhcp-ddns

 It is essential to also modify configure to not require dependencies that
 are not needed. In particular, sqlite is not needed for DHCP. botan is
 only needed for dhcp-ddns.

 Also see follow up ticket #3256.
