[chrisfoulds]

I needed this an option so quickly hacked this together with meets my needs, feel free to use or destroy. I have not done a iOS version but people should get the idea

extendediconbutton.cs
using Xamarin.Forms;

namespace testproject
{
    /// <summary>
    /// Defines the <see cref="ExtendedIconButton" /> control.
    /// </summary>
    /// <seealso cref="Xamarin.Forms.Button" />
    public class ExtendedIconButton : Button
    {
        public static readonly BindableProperty IconProperty =
                            BindableProperty.Create("Icon", typeof(string), typeof(ExtendedIconButton), "");

        public string Icon
        {
            get { return (string)GetValue(IconProperty); }
            set { SetValue(IconProperty, value); }
        }
    }
}
