A lot of GPLv2+ and GPL+ software as well as things under other licenses
in Fedora link to GPLv3+ libraries and I believe that's not considered a
problem as long as the former licenses are "upgradable" to GPLv3+ (which
GPLv2 is not).  For an example, see what links with readline:

repoquery --repoid=rawhide --qf="%{NAME}: %{LICENSE}" \
    --whatrequires --exactdeps "libreadline*.so*"

(Yep, there are some potential problem cases in that list as well, at
least the GPLv2 ones.)
