Here's what I use:

For CVS, there are some newlib checkout instructions online, but:

	cvs -z3 -d :pserver:anoncvs at sources.redhat.com:/cvs/src login

[hit enter, no password]

	cvs -z3 -d :pserver:anoncvs at sources.redhat.com:/cvs/src co newlib

Then to build (modified instructions from a script I use):  

src=$(pwd)/src/newlib
bld=$(pwd)/src/spu-obj
mkdir ${bld}
cd ${bld}

${src}/configure --prefix=/usr --mandir=/usr/share/man \
	--infodir=/usr/share/info --disable-shared --disable-threads \
	--disable-checking --with-headers --with-system-zlib \
	--disable-multilib --disable-nls \
	--enable-version-specific-runtime-libs
	--program-prefix=spu- \
	--target=spu > cfg.out 2>&1

make -j4 > make.out 2>&1

# And then as root:
sudo make install

The above will overwrite your current SPU newlib install (in /usr/spu),
this is not as bad as overwriting you glibc install, since you can just
re-install the newlib rpm if something is borken.

And then spu-gcc will just work ... I never figured out how to use a
different install prefix.

You can also build spu-gcc and newlib at the same time by adding a symlink
to the gcc directory, and then building.
