Mike Hommey 9982192790 Bug 1322025 - Provide variants of host and target that depend on --help. r=chmanchester 
We want to avoid giving --help dependencies to host and target, so that
they we don't spawn config.guess and config.sub when running configure
--help, and don't need to reach out to the which module to find a
suitable shell to execute them.

So, when --help is given, we return a fake host/target namespace, and
avoid the config.guess/config.sub-invoking code being executed.

Then, by giving the --help option to the linter, it can properly find
that the config.guess/config.sub-invoking code doesn't need the
dependency on --help.

This effectively unbreaks configure --help after bug 1313306.
