When Clang is used to test fortify glibc build configured with
--enable-fortify-source=N
clang issues errors like
In file included from tst-rfc3484.c:60:
In file included from ./getaddrinfo.c:81:
../sysdeps/unix/sysv/linux/not-cancel.h:36:10: error: reference to overloaded function could not be resolved; did you mean to call it?

because clang fortify support for functions with variable arguments relies
on function overload. Update not-cancel.h to avoid __typeof on functions
with variable arguments.
