* for backwards compatibility with older NDK-generated binaries.
*
* For newer ones, 'atexit' is actually embedded in the C
* runtime objects that are linked into the final ELF
* binary (shared library or executable), and will call
* __cxa_atexit() in order to un-register any atexit()
* handler when a library is unloaded.
*
* This function must be global *and* hidden. Only the
* code inside the same ELF binary should be able to access it.
