Hi, damn, it's that easy!
It was the .config file, I added (as root) a symlink to dir/.config to let some other
application check if some Kernel-options are set, then the permissions of this symlink
prevented make mrproper from removing it.

For what purpose is this check? I can't point the other application to kerneldir/dir
because it also greps in kerneldir/Makefile for the kernel-version.

Thanks
Stefan
