If all you want is a cross compiler to make a kernel why not try this 
procedure ?

Tested with :

dietlibc-0.28 or dietlibc cvs

untar all sources


./configure --prefix=/usr/local/powerpc-linux --target=powerpc-linux

make install


./configure --prefix=/usr/local/powerpc-linux --target=powerpc-linux 
--with-ecos --disable-nls --enable-threads=posix --disable-shared 
--enable-languages=c --with-headers=../dietlibc/include

make install

There might be a little error in gcc/unwind-dw2-fde-glibc.c and 

I can't remember the exact errors in those two files, but, hopefully 
those should be easy enough to fix.

Once you work around the slight inconsistency between dietlibc & gcc in 
those two files, and make install, you should have a full toolchain in 

I had been thinking about making a small script for kernel people such 
as yourself, who wanted just a toolchain for kernel cross compiles.
Maybe I'll do that.

But, in any case, the above procedure gives me a 3.4.2 which is quite 
happy to compile a 2.4.28-rc3 (though I haven't tried out the denx 
2.4.25... but, I can't see why that would fail).

Hope this helps.
