	'supports_pid_to_exec_file'.
	* target.cc (process_target::pid_to_exec_file): Define.
	(process_target::supports_pid_to_exec_file): Define.

	Update the derived classes and callers below.

	* server.cc (handle_qxfer_exec_file): Update.
	(handle_query): Update.
	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::supports_pid_to_exec_file): Define.
	(linux_process_target::pid_to_exec_file): Define.
	* linux-low.h (class linux_process_target): Update.
