Get a rust cross-compiler for Windows

We want to build our own rust compiler for building then the Firefox and tor rust parts.

Okay, a patch for review is up at bug_25894 (https://gitweb.torproject.org/user/gk/tor-browser-build.git/commit/?h=bug_25894&id=5d6c53155f6fc8d49185dde166ac0471ba2347ae) in my public tor-browser-build repo. It needs #25862 (moved) and #25832 (moved) fixed before, though (which we want to have anyway for switching to ESR 60 I think).

The 32bit cross-compilation has been a huge pain in the butt because it is essentially broken right now. For details, see: https://github.com/rust-lang/rust/issues/12859. Thanks to the help of Alex Crichton and Manish Goregaokar I was able to come up with a minimal patch that works around that problem.

I verified that the resulting x86_64 Rust toolchain is able to compile the necessary Rust bits shipped in ESR 60.

This patch looks good to me. I rebased it on master and #25832 (moved), fixing the conflicts with the macOS patch: https://gitweb.torproject.org/user/boklm/tor-browser-build.git/commit/?h=bug_25894_v2&id=4d5e3d2ba5422b931a2e32a9498feabec6ecc23e

And I am now trying a build of rust with this branch.

Moving review tickets to June.
