Log Message:
Correct handling of __cxa_atexit(a,b,NULL) in libc

In the NetBSD implementation and suggested by Itanium C++ ABI, we wrap
the atexit(x) call as __cxa_atexit(x,NULL,NULL).

__cxa_atexit() is an internal function for the usage of C++.

Correct a bug that __cxa_atexit(x,y,NULL) is handled in the same way as
atexit(x) (which is simplified to __cxa_atexit(x,NULL,NULL).

This misbehavior has been detected in the Thread Sanitizer port to NetBSD.
