Support "mingw" generically as a Windows OS architecture (support for aarch64-mingw-ucrt)

[johnnyshields]

Currently the logic for detecting mingw is too strict. It needs to be loosened to support upcoming aarch64-mingw-ucrt architecture. See this PR: oneclick/rubyinstaller2#399

See also: #8379

@deivid-rodriguez can you please take a look at this as well as PR #8379? I'm trying to figure out the direction I should go here... I'm thinking possibly we should make "windows" something more akin to how generic "ruby" platform works today (so basically "windows", "java" and "ruby" are the 3 generic platforms.)

Thank you @johnnyshields for working on this issue and notifying me! I can confirm it fixes platform mapping issue in oneclick/rubyinstaller2#399 . 👍

[deivid-rodriguez]

I'll look into this @johnnyshields 👍, thanks!

In my opinion using universal-mingw, or universal-mingw-ucrt, or explictly arm64ec-mingw-ucrt & arm64x-mingw-ucrt would be better than mingw for precompiled ARM64EC or ARM64X windows binaries, similar to what universal-darwin does for Mac universal binaries. This gives us better consistency on the arch-os-variant pattern, with platform ruby and java being only exceptions.

I’d be happy to see that -ucrt become implicit for mingw, similar to how -gnu is implicit for linux. However, this is a potentially breaking change for older ruby versions built with MSVCRT, similar to how implicit linux has been a problem for *-linux-musl platform.

@deivid-rodriguez, the Ruby Installer for Windows ARM is now available 🎉 It would be great if you could help look at this soon so we can start using Windows on ARM?

[deivid-rodriguez]

Yep, thanks for the ping. I was planning to start looking into this this week.

[deivid-rodriguez]

@johnnyshields I started looking into this, and I ended up introducing a fair amount of additional changes, so I created a separate PR to supersede this one. See #8428. I tried to implement the approach suggested by @ntkme. Please give it a try!

Closing in favor of #8428.
