* callback.c (default_callback): Initialize target_endian.

Browse source 
(cb_store_target_endian): Renamed from store, new first parameter
	host_callback *cb, drop last parameter big_p.  Take endianness
	from cb.
	(cb_host_to_target_stat): Change to use cb_store_target_endian.
	Remove variable big_p.
	* nrun.c (main): Initialize default_callback.target_endian.
