Ah, right, in your series `bindgen` will point to the new one while
the method will return the `core::ffi` one which might be still `i8`
in some targets.

It would be nice to get a way to modify the target for `u8`, i.e.
`-Cunsigned-char` or a "target modifier" or similar.

Added an entry with some links in our `rustc` list at
https://github.com/Rust-for-Linux/linux/issues/355.
