Subject: [PATCH] constify to_rcmd

This makes the "command" parameter of the to_rcmd target method const.

2014-06-16  Tom Tromey  <tromey@redhat.com>

	* target.h (struct target_ops) <to_rcmd>: Make "command" const.
	* target.c (debug_to_rcmd, default_rcmd): Update.
	* target-delegates.c: Rebuild.
	* remote.c (remote_rcmd): Update.
	* monitor.c (monitor_rcmd): Update.
