I learned something today.
It looks like the "or later clause" is a built in option, but not a built in default, of the GPLv2. With that I mean that the meaning of that phrase is explained in the 9th clause.
However, you can "upgrade" LGPL code to GPL, see LGPLv3 "2. Conveying Modified Versions".
There is a FLOSS license that has an implicit upgrade to new version clause: the Mozilla Public License, see "6.2. Effect of New Versions" in MPLv1.1.
