After investigating a problem reported by Franck Julien <FranckJ@cxr.fr>,
I discovered that when specifying -m68000 and -msoft-float to gcc 2.95.2,
it decides that the proper multilib variant is the default one which is
compiled for the m68020 and hardware floating point. This appears to be
because there is no 68000/soft-float library variant. This problem
applies to all m68000 class CPUs options including -m68302.
