Comment:
I guess you mean the changes to _vulkan_drivers and _dri_drivers. Those are not unrelated. Meson complains about empty values. I am sure [this commit](https://github.com/mesa3d/mesa/commit/d32144602c1dfd507f07774ce906dc25d2697da0) is the reason.
Either I avoid the leading comma or I need to change meson_options.txt through a new patch or there is another way.
I left _gallium_drivers untouched because that one was not triggering the error.

What is your suggestion to solve this?
