* cris/crt0.S: Use jump, not ba, to skip the interrupt table. Use
"setf", not "nop", for common_v10_v32 compatibility.
Move out interrupt table to irqtable.S. Include here for non-ELF.
* cris/irqtable.S: Extracted from cris/crt0.S. Provide per-entry
weak default stub definitions.
* cris/crtn.c: Use "setf", not "nop", for common_v10_v32
compatibility.
* cris/setup.S [__arch_common_v10_v32]: Return.
* cris/Makefile.in (BSP_OBJS): Add irqtable.o.
