gcc-rs is one of two projects for bringing Rust to gcc. gcc-rs is the more ambitious of the two, with an entirely new frontend. There is also rustc_codegen_gcc (https://github.com/rust-lang/rustc_codegen_gcc) that keeps the rustc frontend, and only swaps out LLVM for GCC at the codegen stage.
You can also use rustc as a frontend to GCC through rustc_codegen_gcc.
Why not use this instead?
That's rather rustc_codegen_gcc. gcc-rs is more for people who don't like LLVM and/or Rust.
There is also a project for rustc to use GCC instead of LLVM for codegen.
