As of this writing, recent Rust nightly builds include a version of the libc crate that expects wasi-libc to define the following global variables, but wasi-libc defines them as preprocessor constants which aren't visible at link time, so we need to define them somewhere. Ideally, we should fix this upstream, but for now we work around it.
This commit also addresses an unused field warning.
