code using `__cxa_atexit()` I suspect it won't do that now either. So it
probably has to be enabled explicitly.
I think that `--enable-__cxa_atexit` is sufficient. I've enabled it by
default for Haiku in gcc/config.gcc

problem that it won't work for executable add-ons -- `__cxa_finalize()`
will not be called for them.
Are there executable and non-executable add-ons? For example filetype add-
on for tracker is build with `-nostart` (`-shared`), so it will work. If
there are executable add-ons, we can introduce -addon flag for gcc.
