[PATCH] libstdc++: Fix the return type of __cxa_finalize according to the Itanium C++ ABI

[Fangrui Song]

Alternatively, we can delete it, because no user code should call it.
It may be weird that libc is expected to define this function.
This function is a language runtime interface that has nothing to do
with a libc.
