The non-MMU m68k code has never supported FPU hardware. To help in merging common code create a configation setting that signifies if we are builing in FPU support or not. This switch, CONFIG_FPU, is set as per the current use cases. So it is always enabled if CONFIG_MMU is set, and disabled otherwise. With a little extra code it will be possible to disable it on the classic m68k platforms as well, and to enable it on non-MMU platforms that do have hardware FPU.
