This patch implements support for powerpc-*-windiss. WindISS is Wind
River's instruction-level simulator. (The right way to think about
WindISS is that it is an operating system; it comes with include
files, a C library, and a simulator.)
Ben Elliston has already approved the config.sub change, and has
likely already committed it.
May I commit the changes below?
