The whole point of target descriptions, and the thing we've been going
to so much trouble to implement for the past month, is that this
negotiation is not supposed to be needed. Why does it matter what GDB
supports? If there are new registers that GDB does not know about,
in the target description supplied by gdbserver, then GDB will not use
them specially for debug info or function calls. But it will
otherwise handle them fine.
