toolchain: report missing ports at once Previously, ports that were needed for a scenario and that were not prepared or outdated, triggered one assertion each during the second build stage. The commit slots a mechanism in ahead that gathers all these ports during the first build stage and reports them in form of a list before the second build stage is entered. This list can be used directly as argument for tool/ports/prepare_port to prepare respectively update the ports. If, however, this mechanism is not available, for example because a target is build without the first build stage, the old assertion still prevents the target from running into troubles with a missing port.
