Subject: [PATCH] BUILD: prepare the makefile to skip format lines in SUBVERS
 and VERDATE

We're going to put format lines in these files for use by git archive,
so let's ensure that the current default format still works. For this
we'll use two lines and only take the first one without a format tag.
