After repo sync today, authpolicy failed to build two times but succeeded at the third try.  (dosbin: /build/auron_paine/var/cache/portage/chromeos-base/authpolicy/out/Default/authpolicy_parser does not exist)  I think we should fix that to prevent random breakage for random people / the commit queue.

Retrying emerge of chromeos-base/authpolicy-9999.
