* Makefile.in (SIM_OBJS): Add sim-load.o.

Browse source 
* interp.c (target_byte_order): Delete.
	(sim_kind, myname, little_endian_p): New static locals.
	(init_pointers): Use little_endian_p instead of target_byte_order.
	(sim_resume): Likewise.
	(sim_open): Set sim_kind, myname.  Set little_endian_p from -E arg.
	(sim_load): Return SIM_RC.  New arg abfd.  Call sim_load_file to
	load file into simulator.  Set start address from bfd.
	(sim_create_inferior): Return SIM_RC.  Delete arg start_address.
