	  For abiv2 we couldn't use "trap 1" as user space bkpt in gdbserver, because
	  abiv2 is 16/32bit instruction set and "trap 1" is 32bit.
	  So we need a 16bit instruction as user space bkpt, and it will cause an illegal
	  instruction exception.
	  In kernel we parse the *regs->pc to determine whether to send SIGTRAP or not.
