From: Arnd Bergmann <arnd@arndb.de>
The generic __div64_32() definition is built on all architectures that don't provide this as a macro. m68k however neither defines nor requires __div64_32, so it should define an empty one to avoid the warning:
lib/math/div64.c:31:32: error: no previous prototype for '__div64_32' [-Werror=missing-prototypes]
