See comments https://github.com/rust-lang/libc/pull/194. Note on struct utsname: Neither using a constant, nor a conditional macro seems to work, so I just created an ugly utsname with conditions on each field. This should also fix the CI fallout. #[cfg] on macros doesn't work? As DragonFly only supports one platform, I merged x86_64.rs into dragonfly/mod.rs.
