    libstdc++: Correct notes about std::call_once in manual [PR66146]
    
    The bug with exceptions thrown during a std::call_once call affects all
    targets, so fix the docs that say it only affects non-Linux targets.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/66146
            * doc/xml/manual/status_cxx2011.xml: Remove mention of Linux in
            note about std::call_once.
            * doc/xml/manual/status_cxx2014.xml: Likewise.
            * doc/xml/manual/status_cxx2017.xml: Likewise.
            * doc/html/manual/status.html: Regenerate.
    
    (cherry picked from commit e6836bbbd7a01af0791c02087e568b4822418c0d)
