Jochen and I considered two methods of breaking the circularity concerning
building spu-gcc and spu-newlib.  The problem is that spu-gcc needs spu-newlib
during build, whereas spu-newlib needs spu-gcc during its build.  The two ways
of solving this are
(a) do a build on a unified source tree for gcc and newlib, xor
(b) provide some bootstrap gcc compiler to build newlib, which can then be used
to build spu-gcc.

After some investigation we found that (a) is quite brittle.  None of the
configurations of gcc+newlib (that we tried) build in a unified tree. 
Therefore we have opted for (b).

A simple spu-gcc-bootstrap is available here:

and a spu-gcc which conflicts with spu-gcc-bootstrap is available here:
