Accidentally removed with earlier commit. Although rather than simply
adding the check for all platforms, use the same heuristics as we do in

Namely: pthread-stubs is a thing only for BSD platforms. Everyone else
should have lightweight pthread API in their C runtime library.
Fixes: 4ecd1ef010b ("xf86drm: fix null termination of string buffer")
