I have sometimes seen a "+" or a short-commit-sha appended when
building kernel in a local git repository with uncommitted/committed
changes.
Also i suppose one could run make LOCALVERSION=<unique-string-here> to
help identify a kernel image by the embedded <unique-string> if
required at a later time.
As the image name is one of the first things to be printed in the
kernel/dmesg logs, it helps map error logs to their respective builds.
