m68k: Add memcmp() declaration 



There is a global definition of memcmp() that gets built on m68k but is
never used and causes a warning because of the missing prototype:

    lib/string.c:671:15: error: no previous prototype for 'memcmp' [-Werror=missing-prototypes]

Add the corresponding declaration to avoid the warning.
