Native ABI do not need signal conversion, only emulators may want this. Usually emulators implements its own sv_sendsig method. For now only ibcs2 emulator does not have own sv_sendsig implementation and depends on native sendsig() method. So, remove any extra attempts to convert signal numbers from native sendsig() methods except from i386 where ibsc2 is living.
