Subject: [PATCH 3.2 53/87] m32r: fix m32104ut_defconfig build fail

3.2.77-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Sudip Mukherjee <sudipm.mukherjee@...il.com>

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.
