What I'm trying to say is this: Programs like Git already link against
libgcc, and this has to be permitted by the GPL version 2 (otherwise
we couldn't distribute them). But libgcc is GPLv3 plus another type
of linking exception, so maybe we can use the reasoning which allows
to link us against libgcc to come up with a way to link against
