Comment:
we should fix the driver search path according to https://github.com/void-linux/void-packages/pull/27269 while at it

basically remove

```
case "$XBPS_TARGET_MACHINE" in
        i686) configure_args+=" -Ddri-drivers-path=/usr/lib32/dri";;
esac
```

and add `-Ddri-drivers-path=/usr/lib${XBPS_TARGET_WORDSIZE}` to `configure_args`
