For those libs, another option IIRC was VirtualBox GL provider.

Check the ogl-select (or was it opengl-select?) service which sets the symlinks at runtime. By default it is based on (iirc) smf instance properties; I toggled that value in dual-booted vm/native systems based on prtconf output with an early init script way back when.
