binfmt_misc problems in ubuntu18.04 under docker
https://stackoverflow.com/questions/54951262/binfmt-misc-problems-in-ubuntu18-04-under-docker
Ignore those warnings because it doesn't make sense to register binfmt on the host while the image is being built.
Support for unprivileged docker daemon #104
https://github.com/rust-embedded/cross/issues/104
In principle we can set up the binfmt_misc stuff outside docker then we wouldn't need that privileged docker call but I never got around to implement that. Setting binfmt_misc outside docker would still require root privilege though.
