[PATCH] m32r: fix m32104ut_defconfig build fail

[Sudip Mukherjee]

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.

It was reported long time ago. But I think  no-one cared. You can find
it at:

And FYI, i have contacted Renesas asking them about how to procure a
board to test this arch. Still waiting for a reply.
