The function unresolved-module-symbols returns a list of foreign symbol names, each of which cannot be resolved in the currently known modules.
If module is nil, then list includes only those names not associated with a module.
If module is :all, then list includes the unresolved names in all modules and those not associated with a module.
If module is a string, then it names a module and list contains only the unresolved symbols associated with that module.
