- switch from %%{_libdir}/%{name} as libexecdir to regular old
        %{_libexecdir} (part of #225847)
    - remove explicit configure arguments to use bzip2 and readline, which are
        the default and trigger errors when not present, but continue to
        explicitly request zlib so that we don't fall back to the internal one
        if something ever looks "off" about the system copy (part of #225847)
    - convert the ru manual and doc files to UTF-8 (the ones which aren't
        already, rpmlint)
