    libgomp GCN plugin: Clean up always-empty 'PLUGIN_GCN_CPPFLAGS', 'PLUGIN_GCN_LDFLAGS'
    
    After recent commit d6adba307508c75f1ccb2121eb1a43c9ab1d4056
    "libgomp GCN plugin: Clean up unused references to system-provided HSA Runtime
    library", these aren't set anymore.
    
            libgomp/
            * plugin/Makefrag.am (libgomp_plugin_gcn_la_CPPFLAGS): Don't
            consider 'PLUGIN_GCN_CPPFLAGS'.
            (libgomp_plugin_gcn_la_LDFLAGS): Don't consider
            'PLUGIN_GCN_LDFLAGS'.
            * plugin/configfrag.ac (PLUGIN_GCN_CPPFLAGS, PLUGIN_GCN_LDFLAGS):
            Remove.
            * Makefile.in: Regenerate.
            * configure: Likewise.
            * testsuite/Makefile.in: Likewise.
    
    (cherry picked from commit 91a6dcd14915181b4bce51cd44b56a3e9f9d35d8)
