Yes, but strerror_r is available in posix 2001, and gai_strerror is not
said to be non-threadsafe, so I guess it means it has to be.  I guess we
can thus safely assume that we can build a brlapi_strerror_r from that
that is threadsafe on all current systems.

Currently that's only driver and model names. I don't think we want to
use it for more than that.
