I see no difference between this scenario and a classic C program that 
supports both OpenSSL and GnuTLS via #ifdef's and `configure' options.  

Or a C program linking against an LGPL'ed library which links against 
libssl.  If the library is modified to use GnuTLS instead, the program 
would still continue to work with that variant of the library 
interchangably (provided it is API/ABI compatible, of course).  If the 
program is using the gnutls-linked variant of the library, it needs no 
exception.  If it is using the openssl-linked variant, it does because of 
the indirect linking with libssl.
