gcc-4.7.sh should go. You should build a compiler with multiarch support,
recompile libc and friends in order to place the libraries there. That was
imho the point where I took a break :) So that could end up in work…

Ehm. Multiarch is okay. It will place the libraries under
/lib/powerpc-linux-gnuspe/. That is okay. So you can install them on amd64
while cross compiling or so. We want multiarch :)
Now we don't have and it looks that we won't have a 64bit CPU doing SPE
floating point that means we don't want multilib. Please remove those from
your gcc-patches. I think my old ones did not have those included.

Could you be more specific here please? I see 1.49.0-3.1 at
which looks fine. The boost-defaults package is 22.214.171.124. I don't see 126.96.36.199
