Module drivers 

Host directories that supply GPU and system libraries.

A bundled loader has its compiled-in search paths scrubbed, so anything the host must still provide (libcuda, libvulkan, libGL, libva) has to be named explicitly. The packed runtime and onelf run both need the same list, and previously kept two copies in sync by comment.

Functions

host_driver_paths

Host driver and system library directories for arch, in descending priority, filtered to those that exist.
