I think it is a bug in the Objective-C compiler. For ABIs with the
copy relocation, like ia32, a dynamic data symbol may have to have
size and type to work correctly. The Objective-C compiler should
either don't generate __objc_class_name_NXConstantString or output

	.type	__objc_class_name_NXConstantString,@object
__objc_class_name_NXConstantString:
.L???:
	....
	.size	__objc_class_name_NXConstantString,.L???-__objc_class_name_NXConstantString
