[Bug libobjc/18575] New: objc_class subclass_list and sibling_class not filled out after dlopen

["ratmice at yahoo dot com" <gcc-bugzilla at gcc dot gnu dot org>]

after dlopen on a shared library with objc classes
__objc_resolve_class_links() isn't called until an object is sent a message for
the first time or a class poses as another class.

i currently call this private function after loading them, but not sure if it
could be done in the ctor (if there is a way to do this without traversing the
class list twice?)
