	'supports_get_tls_address'.
	* target.cc (process_target::get_tls_address): Define.
	(process_target::supports_get_tls_address): Define.

	Update the derived classes and callers below.

	* server.cc (handle_query): Update.
	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::supports_get_tls_address): Define.
	(linux_process_target::get_tls_address): Define.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.cc (lynx_target_ops): Update.
