This adds check for multiprocess before appending 'multiprocess' to reply.
I can see that from the patch. But, why?

If gdbserver doesn't have support for multiple processes, how will it report lack of that feature to GDB?

By querying the target, how else? Something like:

+      if (target_supports_multi_process ())
      strcat (own_buf, ";multiprocess+");

      if (target_supports_non_stop ())
	strcat (own_buf, ";QNonStop+");

(that function doesn't exist today, but it should).

I have created gdbserver for nto to be able to use gdb for nto/linux. One of things this server will not have (at least for now) is multi process support. It will only handle one process a time.

That is different from (like your patch was doing) reporting multi_process support if GDB reports support as well, which is still broken in your example. (and now that you mention it, in all gdbserver targets but linux).

Yes, I realized when I saw your question and revisited the code.
