Created attachment 568472 [details] compressed build log from mesa-18.2.8 To me it seems that this happens, because the ebuild uses llvm-config from the host and not from the target. So, I wonder, is it possible to patch mesa's meson build system in a way that it not only detects cross-deps, but also cross-llvm-config?
