Gold patch to fix common symbol handling

This gold patch ought to fix the problem. Please verify and I'll send it
upstream to binutils.

        * plugin.cc (Pluginobj::get_symbol_resolution_info): Check for
        prevailing definitions of common symbols.
        * testsuite/plugin_test_6.sh: New testcase.
        * testsuite/plugin_common_test_1.c: New testcase.
        * testsuite/plugin_common_test_2.c: New testcase.
