lib: cpp: Do not define __cxa_atexit() for the posix arch

Browse source 
For the POSIX architecture we do not define an
empty __cxa_atexit() as it otherwise would
override its host libC counterpart. And this would
both disable the atexit() hooks, and prevent possible
test code global destructors from being registered.
