Chris probably uses a "single tree" build with newlib and all the other 
stuff needed right there where GCC can find it at cross-build time, so
he's not going to run into this issue.

If you build cross-gcc separately, you'll need to install the runtime
where GCC can find it. I believe I have most of the info needed on my
cross-build HOWTOs for Cygwin and Mingw, but most if it by now woefully
out of date. I'll have to update those sometime very soon.
