Jan,
Do you mean to 
(a) define a new %package spu target in binutils.spec or 
(b) to use the binutils.src.rpm as Source0 in the spu-binutils.spec?

I don't believe (a) is a good option as any upstream stability issues in SPU
could delay the release of new packages for more popular architectures such as
i386 etc...

I've done some initial hacking on (b) trying to have spu-binutils.spec using
binutils%{version}.src.rpm as Source0.  It appears that RPM isn't designed for
such build configurations as, for example, %setup does not know about .src.rpm
files.  One has to manually setup the binutils.src.rpm and then rpmbuild --bc
binutils.spec and finally use the %install and %files directives of
spu-binutils.spec to create the spu-binutils.rpm.  It appears, to me, that the
only advantage of this approach is to maintain spu-binutils.spec as having the
same binutils version as binutils.spec.  This leaves us in the same position as
(a) as we may sometimes need to lag behind the version of binutils built by
binutils.spec.

Overall, I think Jochen's approach is the most straightforward and uses
conventions established by other cross toolsets.
