Error with AMD 570 GPU

[porcuquine]

@keyvank Can you take a look at this?

[keyvank]

@flyworker It seems like Futhark is not able to find your OpenCL runtime. Do you have AMD OpenCL drivers installed on your system? Could you run clinfo on your machine and send the results here? Thanks

I think this is the smoking gun: fatal error: cannot open file '/usr/lib/clc/gfx1010-amdgcn-mesa-mesa3d.bc': No such file or directory

To my knowledge, OpenCL is not supported on Radeon RX 5700 GPUs (or any other Navi GPUs), except possibly with amdgpu-pro (AMDs proprietary stack, which I thought was deprecated).
