Information on [modern] cross compiling is horrible. If I recall,
crosstools is terribly out of date (or at least the website). Have you
looked at crosstoolng (http://freshmeat.net/projects/crosstool-ng/)?
An up to date book, including cross-compilation, would be very
welcomed (hint to Ian and Jonathon).
