[Pkg-rust-maintainers] Cross compiling using debian tools

[Ximin Luo]

It's a lot simpler than that these days Gus. I'd recommend using the instructions I pasted already, they work for everything and not just rustc/cargo itself. It also doesn't require you to know about rustc/cargo specific things like libssl/PKG_CONFIG_ALLOW_CROSS=1, you only have to learn things general to all Debian cross-compilation.
