Subject: configure: add --without-ldap, --without-radius and --without-dbi
 options.

When building for distributions such as Gentoo Linux, or FreeBSD
ports, it's convenient to be able to disable building certain
functionalities even if the dependencies are present, to avoid what
are called "automagic dependendencies".

Adding these parameters solve the issue.
