[RFC 2/4] Fix iq2000-elf sim, default hardware to off.

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

See previous message re frv-elf (1/4); this similarly fails at the
dv_sockser_install declaration in sim/iq2000/tconfig.in.  There's no
HAVE_DV_SOCKSER conditionals here and no other dv-sockser.o artefacts
so maybe there is no further fallout, but I'm disabling sim-hardware
just be consistent with the state before 94c63d78f (2013-03-23) and
with the actions for frv-elf.  That's right, we went from not using
dv-sockser to requiring it without actually using it.  Unfriendly.
Make check-sim for iq2000-elf shows no failures after this - but
that's because it has no test-suite.  At least it builds.

sim/iq2000:
    	* configure.ac: Default simulator hardware to off again
	without emitting errors when off or dv-sockser.o unavailable.
    	* configure: Regenerate.
