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.
