	'supports_qxfer_libraries_svr4'.
	* target.cc (process_target::qxfer_libraries_svr4): Define.
	(process_target::supports_qxfer_libraries_svr4): Define.

	Update the derived classes and callers below.

	* server.cc (handle_qxfer_libraries_svr4): Update.
	(handle_query): Update.
	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::supports_qxfer_libraries_svr4): Define.
	(linux_qxfer_libraries_svr4): Turn into ...
	(linux_process_target::qxfer_libraries_svr4): ... this.
	* linux-low.h (class linux_process_target): Update.
