Answer

I found the problem : the date was invalid.
I modify my function to this

    function updateCookie( langue ) {
        // today + 1 year
        var exdate = new Date().getTime() + (1000*60*60*24*7*52);
        var date_cookie = new Date(exdate).toUTCString();
        document.cookie = 'l='+value+'; expires='+date_cookie+'; path=/';
        location.reload();
    }

And that work on chrome/mozilla on computer and android
