   I suggest you create a combined source tree. This is easiest if you get
the sources using cvs and svn, because then binutils, gdb, newlib and the
simulator are already in a combined tree. But since you probably have the
source tarballs, try something like this:

	mkdir src
	cd src
	tar -jxf gcc-xxx.tar.bz2
	tar -jxf newlib-xxx.tar.bz2
	tar -jxf binutils-xxx.tar.bz2
	tar -jxf gdb-xxx.tar.bz2
	...
	mkdir combined
	cd combined
	ln -s ../gcc-xxx/* .
	ln -s ../newlib-xxx/*
	ln -s ../binutils-xxx/*
	ln -s ../gdb-xxx/*
	...
	cd ../..
	mkdir build
	cd build
	../src/combined/configure --target=powerpc-eabi --prefix=... \
	--with-newlib --enable-sim ...
	make
	make install

   There is some overlap (e.g. libiberty) between the source packages, and
normally you want to use what's in the gcc sources. But I've had a case
where libiberty from gcc was too old to compile binutils and then it should
be OK to use the one from the binutils instead.

   Btw, the target powerpc-eabisim defaults to a setup suitable for producing
binaries to run on the simulator.

   How do you know it doesn't work[1]?
