There is a variable called `_sbdir` that is normally used to find internal
helper scripts located in the source builder...

https://docs.rtems.org/branches/master/user/rsb/configuration.html#configuration

If you add `rtems-kernel-config-check` to `source-builder` it becomes a user
facing tool and needs documentation and a controlled user interface. If you use:

 %{_sbdir}/sb/rtems-kernel-config-check

the helper script is internal to the source builder. Is the script internal?

How are config file errors handled? I normally return `ERROR` or something that
can be checked.

The documented method uses `--with-rtems-bsp=erc32 --with-rtems-tests=yes` ...

https://docs.rtems.org/branches/master/user/start/bsp-build.html#rsb-bsp-build

I prefer we do not changes this. See `--with-<label>`:

https://docs.rtems.org/branches/master/user/rsb/commands.html#set-builder-sb-set-builder

The --with-* method avoids creating a dependency between package configs and the
commandline options, ie this source file.
