https://github.com/FriederHannenheim/void-packages openxr-package
https://github.com/void-linux/void-packages/pull/49294

New package: openxr-loader-1.0.34
<!-- Uncomment relevant sections and delete options which are not applicable -->
This packages the OpenXR loader as well as development files. It is required to run OpenXR applications and games.

I got the available arches from this file at line 40:
https://github.com/KhronosGroup/OpenXR-SDK/blob/main/src/common/platform_utils.hpp
I'm not sure it is exactly right since there armv7a-vfp is supported but I didn't find it in `common/cross-profiles`
