configurable settings for stand-alone simulator.
start-sanitize-sky

end-sanitize-sky
* configure.in: Added X11 search, just in case.
* configure: Regenerated.

* configure : Rebuilt.
* mips.igen : Correct the bfd-names in the mips-ISA model entries.
Add the vr4320 model entry and mark the vr4320 insn as necessary.
little struct.
interp.c: Update. Also add floating point Max/Min functions.
mips.igen: Remove r5900 tag from any floating point instructions.
r5900.igen: Rewrite. Implement *all* floating point insns (except ld/st).

update v850, tic80 and mips simulators.
IGEN - Prepend prefix to more generated symbols and macros
(idecode_issue, instruction_word).
IGEN - Add -Wnowith option to supress warnings about word size
inflicts in input files.
MIPS - Clean up Makefile.in, m16.igen, m16.dc (new), m16run.c (new) so
that a mips16 simulator built using IGEN can be compiled.
For sim/mips, enable multi-sim support when mips64vr5400-elf is target.
For sim/igen, allow specification of a default machine (will need
more work later).
