Building compiler-rt for aarch64-windows is possible and yield a working LLVM cross-compiler to
aarch64-windows.
Tested via:
```
NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 nix-build -E '(import <nixpkgs> { crossSystem = { config = "aarch64-windows"; libc = null; rustc.config = "aarch64-unknown-uefi"; useLLVM = true; }; }).lanzaboote-stub'
```
(can work with any UEFI binary you have at your disposal in your
nixpkgs.)
and then, you can run the UEFI result using QEMU and AArch64 UEFI binaries.

This is for building UEFI binaries, right? Just checking.

It will, it just doesn't for now. This is a draft because no real intention to go somewhere with this, we can close. |

Tested via:
(works with any proper UEFI package that you have at your disposal in your tree, note: I said proper UEFI package, not systemd-boot ELF hackery or GNU-EFI.)
and then, you can run the UEFI result using QEMU and AArch64 UEFI binaries.
Some questions remains if this is viable approach on actual hardware.
