[PATCH 8/8] m68k: don't panic if no hardware FPU defined

[Greg Ungerer <gerg@linux-m68k.org>]

If we boot up and find no hardware FPU we panic and die.

Change this behavior to be that if we boot up and we _expect_ a hardware
FPU to be present then panic. Don't panic if we don't actually expect to
have any hardware FPU.

This lets us compile a kernel without FPU if we really choose too.
