Subject: [PATCH] Move the ARCH sanity check from the depgraph constructor to a
 new validate_ebuild_environment() function and call it before any action that
 requires an ebuild environment (including search, which may result in
 metadata generation). So, --sync, --metadata, and --info are currently the
 only actions that are allowed without ARCH being defined.
