    libstdc++: Fix bootstrap failure with --enable-vtable-verify [PR118981]
    
    The compiler emits code with init_priority(99) for -fvtable-verify=std
    and that creates a section conflict with the uses of init_priority(99)
    that I recently added to src/c++20/tzdb.cc.
    
    Change tzdb.cc to use a different priority to avoid the conflict.
    
    libstdc++-v3/ChangeLog:
    
            PR c++/118981
            * src/c++20/tzdb.cc: Use init_priority(98) instead of
            init_priority(99).
