Really not that familiar with all this. I guess it's caused by the rustup command and something is conflicting with a component already installed locally?

Following rust-lang/rust#75833 and using :

$ rustup set profile default

Fixed the issue. Clearly not related to rustc_codegen_gcc so closing it.
