The status of programs dynamically linking to GPL'd libraries is
indeed disputed, but I don't believe that the Linux kernel situation
is relevant.  They're not linking with someone else's GPL'd library,
but offering their own interpretation of the GPL on their own code.
Since the FSF hold the copyright on this particular library, it would
be polite to follow their interpretation.
