I was in favour of the the explicit driver/st tracking yet it was
nuked with commit 28e84c93bb33dfc8ac5219480b274c84dbd58762
To address the above use-case, we don't need to reinstate the tracking
- it causes a lot of churn.

Off the top of my head - none of the VL code should be build when we
have only a swrast driver.
Can you try and kill that bug, or shall I?
