Big cleanups
    
    /etc is way shorter and less obscuring than %{_sysconfdir}.
    Reorder %configure options.
    Add %configure options for new features.
    Add build dependencies for those features.
    Just build with %make_build.  No need to get fancy.
    When calling perl, we can just use "perl".  Still use the macro for
        actually embedding the path to perl into compiled code.
    Just use the default compilation flags.  The hardened flags are default
        now.
    Start using four space indentation.
