Sorry to disappoint you, but that wont work for two reasons:
1) make config-recursive is flawed by design, because it makes a dependency 
list based on current settings and if you alter dependencies during your 
recursive configuring, it will not update the list.

2) If you hit an interactive configure (not config, configure) target, then 
you will still end up with a dialog. Prime example: print/ghostscript-gpl.

If you wanted to script the first case, you'd do the following in every origin 
that needs updating:
#!/bin/sh

VISITED=

config_port() {
        local ldeps rdeps bdeps
        ldeps=`make -V LIB_DEPENDS`
        rdeps=`make -V RUN_DEPENDS`
        bdeps=`make -V BUILD_DEPENDS`

        make config-conditional
        for dep in ${ldeps} ${rdeps} ${bdeps}; do
                dir=${dep##*:}
                case ${VISITED} in
                        *" ${dir}"*)
                        ;;
                        *)
                        echo "---> $dir"
                        VISITED="${VISITED} ${dir}"
                        cd ${dir}
                        config_port
                esac
        done
}

config_port

Problem with today's modular software: they start with the modules
    and never get to the software part.
