Currently it's implied. It would be nice if there was an easy way just
to fish it out of the env of the docker image as they already have it
set there.

I've been trying quite hard to ensure all the tests can just use LD (see
the hoops I jump in i386 for this). Maybe a prefix config makes more
sense though....
