That is strange -- in theory apt-get should find the appropriate package
(under the condition that there exists a spu-gcc - package for your
Ubuntu version, and you have an "deb-src ..." entry in your
/etc/apt/sources.list (but if that would be missing, apt-get should give
another error message).
Did you install spu-gcc by aptitude/synaptic, or you downloaded the .deb
directly from the web? For "apt-get source" to work you need an "deb-src
..." entry for the package repository from which you downloaded spu-gcc

OK, if you want to compile it yourself:
That's the official documentation: http://gcc.gnu.org/install/
(on the page http://gcc.gnu.org/install/configure.htm you have specific
comments for building a cross-compiler)
However, if you do that, you have to be careful:
- you should NOT install this new, self-compiled compiler in the main
system, but in some special directory (in order not to create
conflicts with the package management system of Ubuntu)
- if you keep the spu-gcc - package installed, you will have TWO
cross-compilers installed - then you have to define which one to use
(e.g. you can use the option "--program-suffix" when compiling gcc in
order to give it a different name)
