I've applied to master, but in a different form. I've first
cherry-picked from the next branch your patch that enables the FLAT_ONE
format, and then applied this patch with just the part that disables
FLAT_SEP_DATA on m68k. I've also added a comment in the Config.in file
itself about why FLAT_SEP_DATA is not available on m68k.

Thanks!

Thomas
