With --disable-sim-hardware (--enable-sim-hardware=no),
whose default was changed to --enable-sim-hardware(=yes) in
commit 34cf511206, building for cris-elf fails as
sim_hw_parse then doesn't exist.
A cris-elf simulator configured for --enable-sim-hardware
(or the default after to the mentioned commit) runs about
2.5x slower than one configured --disable-sim-hardware.
A further 2-5% performance regression was not investigated.
When sim_hw_parse doesn't exist, --cris-900000xx can't be
supported. The best action here is to remove it completely,
so its absence can be identified through --help, but
avoiding littering the code with "#if WITH_HW".
sim/cris:
* sim-if.c (cris_options) [WITH_HW]: Conditionalize
support of option --cris-900000xx.
(sim_open) [WITH_HW]: Conditionalize sim_hw_parse
call.
