LibGL access error through IrrlichtMT

1

Observed on Luanti using IrrlichtMT.

Errors out with

failed to get driver name for fd -1
mesa loader failed to retrieve device information

Falls back to software llvm (?). Huge performance hit.

Tested on bothh Raspberry Pi OS 13 on a Pi 5 (ARM64 with V3DV drivers) and also Debian 13 on traditional x86.

Something that accesses through abstraction (PrusaSlicer, prob via Qt) is complerely unaffected and in fact work on both systems.
