m68k: Kill several external declarations in source files
- Replace external declarations by proper includes where availiable.
The accesses to some symbols had to be modified, as before they were
declared using e.g. "extern int _end", while asm-generic/sections.h uses
e.g. "extern char _end[]"
- Remove unused or superfluous external declarations
