This is because linux-image and linux-headers packages Radxa provides for 4.4.154-111-rockchip-g39b306a41b2d for this board are built incorrectly (broken).
In my case I can’t compile against the kernel headers because some of the binaries in linux-headers-4.4.154-111-rockchip-g39b306a41b2d are compiled for x86 (!):

This was also mentioned in https://github.com/google-coral/edgetpu/issues/42#issuecomment-578393880 and (related) DKMS building error
@jack Radxa, can you provide fixed kernel support packages?
