LLVM += new architecture

For what it's worth, there's bindgen, which automates the process of converting C headers to a Rust interface. It looks like the Rust people aren't using it for libc at the moment, but if you needed it to support a new architecture/libc, you could write a version of the libc crate that used bindgen, or just use bindgen's output as a starting point to add to the hand-written definitions in the libc crate.
