Oh.

The uname approach works, the following is a piece of uname that uses
P/Invoke instead of depending on uname, its part of mkbundle.cs:

using System.Runtime.InteropServices;

        [DllImport ("libc")]
        static extern int uname (IntPtr buf);

        static void DetectOS ()
        {
                if (!IsUnix) {
                        Console.WriteLine ("OS is: Windows");
                        style = "windows";
                        return;
                }

                IntPtr buf = UnixMarshal.AllocHeap(8192);
                if (uname (buf) != 0){
                        Console.WriteLine ("Warning: Unable to detect OS");
                        return;
                }
                string os = Marshal.PtrToStringAnsi (buf);
                Console.WriteLine ("OS is: " + os);
                if (os == "Darwin")
                        style = "osx";

                UnixMarshal.FreeHeap(buf);
        }

        static bool IsUnix {
                get {
                        int p = (int) Environment.OSVersion.Platform;
                        return ((p == 4) || (p == 128));
                }
        }
