Add a way to specify a custom graphdriver priority list during build. This can be done with something like go build -ldflags "-X github.com/docker/docker/daemon/graphdriver.priority=overlay2,devicemapper" As ldflags are already used by the engine build process, and it seems that only one (last) `-ldflags` argument is taken into account by go, an envoronment variable `DOCKER_LDFLAGS` is introduced in order to be able to append some text to `-ldflags`. With this in place, using the feature becomes make DOCKER_LDFLAGS="-X github.com/docker/docker/daemon/graphdriver.priority=overlay2,devicemapper" dynbinary The idea behind this is, the priority list might be different for different distros, so vendors are now able to change it without patching the source code.
