    libstdc++: Fix exports for IEEE128 versions of __try_use_facet [PR108327]
    
    The new symbols need to be exported, as well as some of the
    std::locale::facet::id globals, which are not new but were presumably
    not needed by any inline functions before now.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/108327
            * config/os/gnu-linux/ldbl-extra.ver (GLIBCXX_LDBL_3.4.31):
            Export __try_use_facet specializations for facets in namespace
            __gnu_cxx_ldbl128.
            * config/os/gnu-linux/ldbl-ieee128-extra.ver
            (GLIBCXX_IEEE128_3.4.31): Likewise for facets in namespace
            __gnu_cxx_ieee128.
            * testsuite/util/testsuite_abi.cc: Add to lists of known and
            latest versions.
