[PATCH 2/2] m68k: use new macros for .data.init_task.

.data.init_task should not need a separate output section; this change
moves it into the .data section.

I changed the aligment in both linker scripts to be THREAD_SIZE from
8192 and PAGE_SIZE, respectively. I'd like an ack from one of the
m68k maintainers that this is right.
