Coreutils (dis)armed

More fallout from this.

For example:

Compiling chroot v0.0.1 (file:///tmp/coreutils-master)
src/chroot/../common/c_types.rs:1:43: 1:61 warning: unknown `allow` attribute: `raw_pointer_derive`, #[warn(unknown_lints)] on by default
src/chroot/../common/c_types.rs:1 #![allow(dead_code, non_camel_case_types, raw_pointer_derive)]
                                                                            ^~~~~~~~~~~~~~~~~~

or

Compiling nohup v0.0.1 (file:///tmp/coreutils-master)
