commit 601f1db653217f205ffa5fb33514b4e1711e56d1 upstream.

The build of m32104ut_defconfig for m32r arch was failing for long long
time with the error:

ERROR: "memory_start" [fs/udf/udf.ko] undefined!
ERROR: "memory_end" [fs/udf/udf.ko] undefined!
ERROR: "memory_end" [drivers/scsi/sg.ko] undefined!
ERROR: "memory_start" [drivers/scsi/sg.ko] undefined!
ERROR: "memory_end" [drivers/i2c/i2c-dev.ko] undefined!
ERROR: "memory_start" [drivers/i2c/i2c-dev.ko] undefined!

As done in other architectures export the symbols to fix the error.
