    fix math export/import in docx/rtf
    
    For some reason older gcc versions don't manage to dynamic_cast
    to the necessary cast. I'm not quite sure why, forcing 
sal/osl/unx/module.cxx
    to always use RTLD_GLOBAL does not seem to help. Most probably
    compiler bug. Changing the cast to two simpler ones helps.
