Failed in this build: https://uberchromegw.corp.google.com/i/chromeos/builders/lakitu-paladin/builds/2696

However, none of the CLs there seem to be responsible, and the following build seems to be succeeding (so far).

 * Error: circular dependencies:

(sys-apps/util-linux-2.27.1:0/0::portage-stable, ebuild scheduled for merge to '/build/lakitu/') depends on
 (sys-apps/systemd-225-r7:0/2::lakitu-private, ebuild scheduled for merge to '/build/lakitu/') (buildtime)
  (sys-apps/util-linux-2.27.1:0/0::portage-stable, ebuild scheduled for merge to '/build/lakitu/') (buildtime_slot_op)

It might be possible to break this cycle
by applying any of the following changes:
- sys-apps/util-linux-2.27.1 (Change USE: +build)
- sys-apps/util-linux-2.27.1 (Change USE: -systemd)
