The streamline_config.pl finds all the configs that are needed to
compile the currently loaded modules. After it creates the .config
file, it tests to make sure all the configs that are needed were
set.

It only looks at the configs that are modules, it does not look
at the builtin configs. This causes unnecessary warnings about modules
not being covered.
