Eric Norum <eric@cls.usask.ca> submitted linker script and bsp_specs

for the gen68360 that let it work with ELF and C++ exceptions.  This
was used as the basis for changes to EVERY m68k bsp_specs and linkcmds.
Before this modification is over, the layout of the starting stack,
heap, and workspace will likely be modified for every m68k BSP. Then
they will all be very similar.
