Comment:
I tested locally and the  [`vkcube` cross-build patch applies fine against `Vulkan-Tools` here](https://github.com/KhronosGroup/Vulkan-Tools/commit/e8234991418c5b0536e342bc849d5f8ed9eb6d6f) with `vkcube` and friends appearing in the package, would you mind including it already? Would be great to have this on non-x86 arches :)

Additionally building of `vkcube` has to be enabled for all arches with the following diff:

QEMU build helper is here to "fix":

```
`wayland-scanner` (from `wayland-devel`, adding it to `hostmakedepends` doesn't change anything) could probably be used from host instead of target right? so patching it and upstreaming the fix shouldn't be too bad (probably), didn't look into it though.
