The only other case I can think of where we support multiple libraries
for licensing reasons is readline/libedit, but in that case libedit has
the same API as readline, so we don't require much code duplication,
must some configure magic.

I see the problem with the OpenSSL license:

Of course, we are trading a BSD license with advertizing clause with an
LGPL license. I guess it makes sense.
