The different betwen for the following code:
#include <objc/Object.h>
int main(void)
{
  [Object name];
}

at -funit-at-a-time and -fno-unit-at-a-time is:
the removal of at unit-at-a-time:
___objc_class_ref_Object:
        .long   ___objc_class_name_Object


Now to figure out how to mark this reference as used.
