I finally found a solution. The code basically needs two minor corrections:

1. Wrap all DetailPages in a NavigationPage, but not the MasterDetailPage (see #1, #2 and #3 below).
2. Add an Icon to the MasterPage when on iOS (see #4 below). Don't forget to a the actual PNG(!) to the iOS resources.

The minimum working example is as follows:

public static class App
{
    static MasterDetailPage MDPage;

    public static Page GetMainPage()
    {
        return MDPage = new MasterDetailPage { // #1
            Master = new ContentPage {
                Title = "Master",
                Icon = Device.OS == TargetPlatform.iOS ? "menu.png" : null, // #4
                Content = new StackLayout {
                    Children = { Link("A"), Link("B"), Link("C") }
                },
            },
            Detail = new NavigationPage(new ContentPage { Content = new Label { Text = "A" } }), // #2
        };
    }

    static Button Link(string name)
    {
        var button = new Button { Text = name };
        button.Clicked += delegate {
            MDPage.Detail = new NavigationPage(new ContentPage { Content = new Label { Text = name } }); // #3
            MDPage.IsPresented = false;
        };
        return button;
    }
}
