Help text

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.
