GitLab's MinGW job cannot find `x86_64-w64-mingw32-gcc` when linking gitcore's build script: https://gitlab.com/dscho/git1/-/jobs/16593470275

Although gitcore is a static library, Cargo first links `build.rs` as a host executable. We omitted the GNU MSI's `Gcc` feature, which supplies the required linker and platform libraries: https://github.com/rust-lang/rust/blob/1.96.0/src/etc/installer/msi/rust.wxs
