	Turn process_stratum_target's supports_agent op into a method of
	process_target.

	* target.h (struct process_stratum_target): Remove the target op.
	(class process_target): Add the target op.
	(target_supports_agent): Update the macro.
	* target.cc (process_target::supports_agent): Define.

	Update the derived classes and callers below.

	* linux-low.cc (linux_target_ops): Update.
	(linux_supports_agent): Turn into ...
	(linux_process_target::supports_agent): ... this.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.cc (lynx_target_ops): Update.
	* nto-low.cc (nto_target_ops): Update.
	* win32-low.cc (win32_target_ops): Update.
