GCC backend for rustc is still in a very early state. It is in the process of being merged in main rustc source: rust-lang/compiler-team#442 Currently reusing main rust compiler class and simply remove -Cllvm= argument if any (only for intel asm syntax). Disabling binary until the result is more friendly (currently binary are too big). refs compiler-explorer#2683
