thanks for replying, I tried a powerpc cross compiler from the list you have
send but I always got this error

This kind of error is  usually caused by building for one endianess
then changing endianness in the kernel configuration. The build system
isn't smart enough to realise that it needs to recompile the VDSO when
this happens so you'll get linker errors unless you clean the build
directory with `make mrproper` or similar.

We should probably fix that.
