Probably the easiest (as fully automated...) way is to do it "the Ubuntu
way" (I'm using Debian, so I'm not 100% sure the comands are exactly the
same on Ubuntu)
 - download the source code of the spu-cross-compiler
   should be something like "apt-get source spu-gcc"
   This will download the complete source code, including all
   modifications done by Ubuntu.
 - cd' into that new directory and change the spu.h/spu.c files
   then create the Ubuntu-packages:
   dpkg-buildpackage
   (here, dpkg-buildpackage will check that all dependencies are
   fullfilled. If something is missing, it will tell you the name of
   the Ubuntu-package you have to install).
 - now install the locally generated package spu-gcc.versionnumber.deb
   using "dpkg -i ..."
Then everything should be fine :-)

The same is of course possible with the spu-binutils,.. packages, if you
want to change there something.

HTH,
