Ah, perhaps I wasn't clear. We don't create DT_INIT for both static and dynamic executables. You raise an interesting question though. Traditional static executables cannot have DT_INIT since they don't have a .dynamic section. But static PIE executables can have DT_INIT. So should our self-relocation code attempt to exeute it?
