This is a regression, because a more specific _GLIBCXX_ATOMIC_BUILTINS_4 was
defined (but is no longer available) and now there is defined
ATOMIC_INT_LOCK_FREE=1 (I think think the definition is correct, because there
were available _GLIBCXX_ATOMIC_BUILTINS_{1,2,4} and no
_GLIBCXX_ATOMIC_BUILTINS_8).
The other thing is, std::exception_ptr availability should not depend on the
fact whether the platform has lock-free atomics or not.
