+libstdc++: Remove symbols for new std::call_once implementation [PR 99341]
+
+This removes the new symbols added for the new futex-based
+std::call_once implementation. These symbols were new on trunk, so not
+in any released version. However, they are already present in some
+beta distro releases (Fedora Linux 34) and in Fedora Linux rawhide. This
+change can be locally reverted by distros that need to keep the symbols
+present until affected packages have been rebuilt.
