crosstool for native compiler on new system.

Okay, as far as I understand, it is looking for ld in the gnusperoot
folder, which is not present at that time. I don't know if it needs
to be there at that time or not:

Okay, several hours later, I tried exactly the same thing
without --nounpack
demo-e500-cross.sh followed by demo-e500-native.sh:

Then it stops pretty late in demo-e500-native.sh at:

Then I tried to cd into 
...build-gcc/powerpc-linux-gnuspe/nof/libstdc++-v3/src
and did a 'make all' which worked fine...
So I cannot really see why it stopped... with an EPERM?

But then I don't know how to finish the build. If I try to work without 
--nounpack I end up as yesterday (see above).
So - I got stuck again! :-*

Actually, I am really worried if all that work is really the straight 
way to migrate (completely replace) my gcc-3.3.3+binutils 2.14 without
FP support to the gcc-3.4.3+binutils 2.15 with e500/spe to get our
own code efficiently working on our target.
Is there no easier way to achieve that? Well, I am pretty new to
compiling compilers and it's good to learn while doing things (and to 
get help from others) but I run out of time to try things without
being sure if there is a valuable result in the end. Can you
recommend me 'the way' to go for... It doesn't need to be the
fastest one, but I need to get my work done.
Is there any more literature to read beside gcc.gnu.org/* and the
little crossgcc-wiki?

Is there another way to get efficient code for the MPC8540?

Best greets, and thanks...
