How about just not writing the boilerplate text
to ChangeLog when that file already exists?
Then, if you've created a ChangeLog file to be used
by vc-dwim, bootstrap will never touch it.
(BTW, the second sentence seems incorrect:
I saw no makefile rule for "ChangeLog" in tar.)

 This file is a placeholder. It will be replaced with the actual ChangeLog
 by make dist.  Run make ChangeLog if you wish to create it earlier.
