repair gdbstub to match the gdbserial protocol specification
commit fb82c0ff27b2c40c6f7a3d1a94cafb154591fa80 upstream.
The gdbserial protocol handler should return an empty packet instead
of an error string when ever it responds to a command it does not
implement.
The problem cases come from a debugger client sending
qTBuffer, qTStatus, qSearch, qSupported.
The incorrect response from the gdbstub leads the debugger clients to
not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior.
