Problem you are trying to solve

Can we get target triples going to support Cygwin-style Rust applications for ARM Windows?

While we do technically have aarch64-pc-windows-msvc available, cross-compiling Windows Rust apps from non-Windows hosts is remarkably easier with the windows-gnu target triple variants. So a aarch-pc-windows-gnu target may be easier for many macOS/Linux/UNIX Rust devs to support than aarch64-pc-windows-msvc.

Solution you'd like

Introduce aarch-pc-windows-gnu to the set of available rustup targets, similar to the other windows-gnu targets.
