Sigh, when writing a trait, write a proper trait. Does this patch fix
the problem?

2016-12-01  Ville Voutilainen  <ville.voutilainen@gmail.com>

    The convertible_to traits need to use a variadic catch-all for the
    false-cases.
    * include/std/istream (__is_convertible_to_basic_istream):
    Change the parameter of the false-case of __check to a variadic.
    * include/std/ostream (__is_convertible_to_basic_ostream):
    Likewise.
