It was added in 1.8.0, and we don't change pre-existing config files.
You can diff against macports.conf.default to see what's new/changed.

The usual behaviour will be to build for $build_arch, which defaults to
ppc on all PowerPC machines. If you select the universal variant (which
not all ports have), then the port will be built for $universal_archs
instead.

You should really only change build_arch when nothing is installed,
since dependencies have to have the arch(s) used by their dependents. If
you want to change it again later, you should uninstall all ports first
(or at least all those that are not installed with +universal).
