The GLIBCXX_3.4.35 and CXXABI_1.3.17 symbols should not be added yet,
not until GCC 16.1.0 is close to release.
The symbols for the older symbol versions GLIBCXX_3.4.{30,31,33,34}
are the ones that need to be added.
Also the TLS symbols for __once_call and __once_callable should not be
added (by convention, because those are not present for all
configurations).
