Building Ports: Is there a "make" equivalent for --batch ?

This helps ("make config-recursive"), but depending on options chosen and 
resulting added dependencies, the config dialog can appear again.  So I run
"make config-recursive" repeatedly until it just returns to shell prompt.
That works most of the time.

My biggest reason for doing this is to be able to run the portmaster or make
command with "|& tee build.log" at the end, and config dialog is very
hostile to this.  It is also helpful to be able to allow a long portmaster or
portupgrade, or package build, to run unattended.
