You might be interested in seeing my build scripts for x86-64 cross 
compilation. You can get these via anonymous cvs at www.x86-64.org. They are 
a set of scripts that download cvs versions of binutils, gcc, glibc, gdb and 
the kernel (we have our own x86-64 cvs kernel tree for development) and a 
bunch of packages via ftp. The scripts then compile a cross compilation suite 
and finally use this to compile a working environment for x86-64 simulators. 
It's my intention to change this into a host and target independent cross 
compilation suite. At the moment, I would think that the scripts are very 
close to building to other 64 bit architectures, but there are some 64 bit 
references that I haven't gotten around to removing yet. No x86-64 specific 
parts should be left by now. When I get the script set a bit more cleaned up, 
I'll put out a release of it.

Even though this isn't cross compilation documentation, this is a working set 
of scripts that produce a working cross compiled environment, so one can see 
some of the things you need to do.

I have earlier promised Joseph that I would write the documentation needed 
for cross compilation. While I still have it on my TODO list, I'm not sure it 
will ever get done. I started looking at it only to find out that what I knew 
from x86-64 cross compilation was very inadequate for GCC documentation, 
since this needs to deal with a lot more stuff. The x86-64 cross compilation 
is very easy compared to other builds. (And then I moved from England to 
Denmark which took all my time.) I still don't mind writing some 
documentation for cross compilation. At least this could then be used to 
expand upon by someone who knows about the missing stuff.

Bo.
