We've been running newaliases(8) when cross-building VMs for a long
time, and it's not entirely clear why -- especially since we don't
do it when we're building a native VM image.
If someone knows why running newaliases is important we can add it
back later, but only after newaliases gets unbroken: As of last week
(a3d4ae7cf3) newaliases fails with EPERM on /etc/dma/dma.conf.
This should unbreak VM (and cloudware) cross-builds.
