[Qemu-devel] [PATCH 1/1] Support ppc64le binfmt registration

["Serge E. Hallyn" <serge@hallyn.com>]

This is a part of a patch proposed by jaejunh at
https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1358268
which enables running ppc64le binaries through qemu-user.

Not sure if it's the right way to do it, but it does allow
me to chroot into a ppc64el rootfs on amd64 host.
