[AIX] report_fatal_error on `-fregister_global_dtors_with_atexit` for static init
On AIX, the semantic of global_dtors contains __sterm functions associated with C++
cleanup actions and user-declared __attribute__((destructor)) functions. We should
never merely register __sterm with atexit(), so currently
-fregister_global_dtors_with_atexit does not work well on AIX: It would cause
finalization actions to not occur when unloading shared libraries. We need to figure
out a way to handle that when we start supporting user-declared
__attribute__((destructor)) functions.
Currently we report_fatal_error on this option temporarily.
