Your scripts works fine. Now I only get one pair of diff which are
System.map.mpc7448hpc2.diff  u-boot.map.mpc7448hpc2.diff, because
mpc7448hpc2 failed to build:
"
Configuring for mpc7448hpc2 board...
cc1: error: AltiVec and E500 instructions cannot coexist
cc1: error: AltiVec and E500 instructions cannot coexist

Boards compiled: 1
Boards with warnings or errors: 1 ( mpc7448hpc2 )

".

Other than that, I think all the System.map and u-boot.map keep the same
before and after applying the patch. 

What kind of info do you still expect to see?

Thanks.
