How to build a cross-compiler

[Tom Litrenta]

I downloaded gcc-2.95.1.tar.gz , untared it and got a
directory structure. I then did a
1 - make bootstrap
2 - make install 

and the compiler on a sparc worked fine. Now I want to build
a cross-compiler for a Power PC. The directions in
www.objsw.com/CrossGCC/FAQ specify that I have 
1 - binutilities and
2 - Newlib

What are these, where do I get them . Once I have
them I can convert my directory structure using 
1 - one-tree-1.6.sh and
2 - build-cross.sh

The compiler was easy(but long to build) but the 
building of the cross GCC for the PPC seems much harder!!
