Add mechanism to configure to set the default interface

Browse Source 
In some cases, the user may want to have a different default interface
without the need to always specify it on the command line. Add a
configure option that sets the default interface without the need to
patch the code.

Configure as: ./configure DEFAULT_INTF=name
where name is an interface name that might be enabled with
--enable-intf-<name>.

The configure will enforce that the selected default interface is
enabled.
