The Rust Binder object file is called rust_binder_main.o because the
name rust_binder.o is used for the result of linking together
rust_binder_main.o with rust_binderfs.o and a few others.

However, the crate name is supposed to be rust_binder without a _main
suffix. Thus, override the crate name accordingly.

So the crate name is a special crate attribute (together with
`crate_type, it is forbidden inside `cfg_attr`), so I think it makes
in a sense to put it between the SPDX/copyright block and the crate
docs. I also think you didn't add a newline to put it closer to the
title of the docs, as if it were a title of its own.

On the other hand, it is a crate attribute nevertheless, so putting it
together with the rest looks a bit more consistent, and as a title the
English one is probably the best one to see first anyway:

    //! Binder -- the Android IPC mechanism.

    #![crate_name = "rust_binder"]
    #![recursion_limit = "256"]

Hopefully the crate names are still close to the file names (and I
would really not want people to abuse this...).
