I have come across the same problem recently. I think it's caused by the
plugin shared library using its own instance of the plugin registry instead
of the one from the clang binary. The way I fixed (or worked around) it on
my system was by changing autoconf/ExportMap.map (and rebuilding clang) as
follows:

{
        global: main;
                __progname;
                environ;
                _ZN4llvm8RegistryIN5clang14FrontendActionENS_14RegistryTraitsIS2_EEE4HeadE;

        local: *;
};
