Mark Cave-Ayland 9d35c6ade5 q800: add alias for MacOS toolbox ROM at 0x40000000 
According to the Apple Quadra 800 Developer Note document, the Quadra 800 ROM
consists of 2 ROM code sections based at offsets 0x0 and 0x800000. A/UX attempts
to access the toolbox ROM at the lower offset during startup, so provide a
memory alias to allow the access to succeed.
