[PATCH] m68k: Drop duplicate "core-y += arch/m68k/" rule causing link failures

[Geert Uytterhoeven]

    Makefile:1949: target 'arch/m68k' given more than once in the same rule
    [...]
      LD      vmlinux.o
    m68k-linux-gnu-ld: arch/m68k/kernel/entry.o: in function `system_call':
    (.text+0x160): multiple definition of `system_call'; arch/m68k/kernel/entry.o:(.text+0x160): first defined here
    [...]

All "core-y += arch/<arch>/" rules were dropped from the corresponding
arch/<arch>/Makefiles, but m68k was forgotten.
