iq2000 port

The IQ2000 binutils port is one of the worst offenders regarding compile
time warnings.  eg.

bfd/elf32-iq2000.c:261: warning: `iq2000_reloc_map' defined but not used
opcodes/iq2000-asm.c:68: warning: function declaration isn't a prototype

Also, iq2000_elf_object_p sets bad_symtab, with a comment that
"Irix 5 and 6 is broken."  Huh?  How is this relevant to this target?
