None of these boards enable unibuild, so this is a no-op.
This is a first step in making unified builds (chromeos-config) the
default for all new Chrome OS build targets. We're going to add
"use -unibuild" to all legacy non-build boards (in public and
private overlays, as needed), then we'll add "use unibuild" to
the chromeos make.defaults in third_party/chromiumos-overlay.
Googlers may see
go/unibuild-default, and specifically
TEST=Locally ran ./setup-board for all boards then checked the builds' USE flags.
