remote-sim.c: Send debug output to gdb_stdlog.

Tested by building for --target=arm-eabi, and playing with the debug
output a bit.

2013-09-06  Pedro Alves <palves@redhat.com>

	* remote-sim.c (dump_mem, gdbsim_fetch_register)
	(gdbsim_store_register, gdbsim_kill, gdbsim_load)
	(gdbsim_create_inferior, gdbsim_open, gdbsim_close)
	(gdbsim_detach, gdbsim_resume_inferior, gdbsim_wait)
	(gdbsim_files_info, gdbsim_mourn_inferior): Send debug output to
	gdb_stdlog.
