I don't know that there have ever been good docs for this scenario--our 
well-supported cross-compile scenario is Android, which has its own SDK. 
Cross-compiling other things on Linux without a chroot is a giant PITA. jryans 
did write a good blog post[1] last year about building a 32-bit Firefox on 
64-bit Linux, which might be useful. AFAIK Rust is the easy part, since you can 
just `rustup target add armv7-unknown-linux-gnueabihf` or whatever target you 
need. Getting all the -dev packages for various system libraries is the hard
