If you're building from luxrays source, can you also try disabling image
support and seeing if the error changes?

For a source build, go to scenes/luxball/luxball.cfg, and add:
accelerator.imagestorage.enable = 1

When I do that, I get some errors related to missing built-in functions that
libclc is probably failing to provide:
