Don't build insn-extract.o with rtl checking

As seen in PR98144, building insn-extract.o with rtl checking takes some memory,
and it doesn't work on 32bit architectures at all (PR97314).  Richard suggested
on irc to disable rtl checking for this auto-generated file, like it's already
done for genconditions.c.  Patching it like done for genconditons.c.
