If you're combining GPLv2-or-later works with LGPLv2.0/2.1 works, you'll have
to normalize to some GPLv2-based license (such as GPLv2-or-later), since
LGPLv2.1 requires that for combinations.  You won't be able to carry along
the "OR 3-Clause-BSD" part once the combination is made.  Similarly true with
GPLv2-or-later, but LGPL is the interesting one because it's explicit about
the need to change license notices to GPL notices when you combine.
