On FreeBSD 10, accept(2) states[2] in HISTORY
The accept4() system call appeared in FreeBSD 10.0.
So I guess the bug is that the declaration is nevertheless visible in
the glibc header file used on your Debian system.
The other possibility is that the Debian developers implemented it on
their own, but it somehow fails the configure test (you could check
config.log).
I found a short mailing list thread about this[3].
