I remember fixing a very similar issue with d4ddf22d54f9374715c651aaebda2315e9f89272. The issue was cross-building QEMU does not work, because it's dragging packages built with meson-build-system. Turns out we want to use a native build of QEMU here, so I replaced #$qemu by #+qemu. Now there must be a similar issue somewhere. I'm building your branch to see if I can figure it out. Thanks for sharing your progress! Mathieu
