Hi,

I attached the very simple patch that will make the requested
functionality work in qemu. One can now do something like this:

export QEMU_LD_PREFIX=/tmp/debian-sid-armel
fakeroot fakechroot chroot /tmp/debian-sid-armel dpkg --configure -a

and it works! without anything in /etc/qemu-binfmt/arm :D

cheers, josch
