I'm not sure but I expect this warning is caused by the FreeBSD resolv
library, which for some reason tries to intelligently apply
pthread-based multi threading when resolving DNS names.

This warning is unrelated and will disappear after our current
lwip/lxip rework is finished. It only hints that this code uses a
deprecated but still functional feature of the Genode API.
