Subject: [PATCH] Conditionally use Unix epoch time for build incremental

Incremental version is used in various places to invalidate caches.
Setting BUILD_NUMBER directly causes unnecessary rebuilds due to
environment variable changes, so simply set it to Unix epoch unless
BUILD_NUMBER is explicitly set.
