mkstemps() has been brought into 3-STABLE, so this isn't needed here

anymore as building -CURRENT sources on 3-STABLE was the reason for the
previous revision adding this.

Note that since the GCC Project moved mkstemp.c from GCC's world to
libiberty, we no longer support building -CURRENT sources on non-FreeBSD
boxes unless that box has a very simular libc mix as FreeBSD.
