The _ZZZ1fB7__test1vEN1T1gEvE1x symbol is only output with the ABI tag
when cxa_atexit is available for use. On targets that default to
-fno-use-cxa-atexit, the test fails gratuitously. Add an explicit
-fuse-cxa-atexit, along with a requirement for cxa_atexit support.
Regstrapped on x86_64-linux-gnu. Also tested with aarch64-elf and
arm-eabi with gcc-15. Ok to install?
for gcc/testsuite/ChangeLog
* g++.dg/abi/abi-tag18a.C: Require and enable cxa_atexit.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
