    libstdc++: Define deleted wchar_t overloads unconditionally [PR 98725]
    
    We don't need to have <wchar.h> support in order to delete overloads
    for inserting wide characters into narrow streams.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/98725
            * include/std/ostream (operator<<(basic_ostream<char, Tr>&, wchar_t))
            (operator<<(basic_ostream<char, Tr>&, const wchar_t*)): Always
            define as deleted. Do not check _GLIBCXX_USE_WCHAR_T.
    
    (cherry picked from commit 9a89281c4005a51eeed058ca66bcce8df1dd1b24)
