[RFC 3/4] Fix sh64-elf sim, default hardware to off.

[Hans-Peter Nilsson]

See previous message re iq2000-elf; this similarly fails at the
dv_sockser_install declaration in sim/sh64/tconfig.in, disabling
simulator hardware to be consistent with the state before 94c63d78f
(2013-03-23) and with the actions for frv-elf and iq2000-elf.  Make
check-sim for sh64-elf shows no regressions (25 failures; 357 expected
passes) compared to bf3d9781ec049 (before the recent config.in regen,
after sim-hardware mostly-enabled) and eed23bb4a1 (before the
sim-hardware mostly-enabled; 2013-03-23).

sim/sh64:
    	* configure.ac: Default simulator hardware to off again
	without emitting errors when off or dv-sockser.o unavailable.
    	* configure: Regenerate.
