Fixed x86 lib fetch for windows.

[rdbo]

It should already be i686 according to Rust platform supports... https://doc.rust-lang.org/nightly/rustc/platform-support.html

I still getting issues while trying to build it for i686 target. Maybe I do something wrong? Build command:

cargo run --target i686-pc-windows-msvc --release

error: failed to run custom build command for `libmem-sys v5.0.1 (https://github.com/rdbo/libmem?branch=master#84e6344b)`

Toolchain is nightly as you mentioned, nightly docs. (although it remains same algorithm of acquiring all those variables) Swapping to resolves my issue all linked and working. Can you provide me some solution for my case @rdbo ? According to docs https://doc.rust-lang.org/reference/conditional-compilation.html I have found some way out using env variables. This way we will extract i686 as it goes first over according to a pic you showed me over in your reply.

let target = env::var("TARGET").unwrap();
let parts = target.splitn(4, '-').collect::<Vec<_>>();
let arch = parts[0];

Looks fitting for your workflow file building mechanism.
