When use with parameter "-machine virt,accel=hvf -cpu host" to run launch a emulator, it can't set breakpoint and will report error: "warning: failed to set breakpoint site at 0xffff800081bf03cc for breakpoint 1.1: error: 34 sending the breakpoint request" +but if not use with parameter "-machine virt -cpu cortex-a57"，The breakpoint can be set successfully. + +2.
