Another option is to match one extra character:

remote-bin-hos%: bin
        ...

Of course this also matches targets like remote-bin-hosX etc.  If you
can't live with that then your only option is to declare both rules and
either duplicate the recipe or put the recipe in a variable and use
that in both rules, as Philip mentioned.
