    libstdc++: Support single components in name of chrono::current_zone()
[PR108211]

    We currently only handle the case where /etc/localtime is a symlink to a
    path like ".../Etc/UTC" and fail for ".../UTC". This makes both work.

    libstdc++-v3/ChangeLog:

            PR libstdc++/108211
            * src/c++20/tzdb.cc (chrono::current_zone()): Check for zone
            using only last component of the name.
