Yes, it can. In config/rs6000/rs6000.c replace

	if (BYTES_BIG_ENDIAN && optimize_size)
	  target_flags |= MASK_MULTIPLE | MASK_STRING;
by
	if (BYTES_BIG_ENDIAN && optimize_size)
	  target_flags |= 
	    (MASK_MULTIPLE | MASK_STRING) & ~processor_target_table[j].target_disable;

Best regards,

Do you suppose the reason the ends of the `Intel Inside'  logo  don't
match up is that it was drawn on a Pentium?
