Hi,

Before relocate_sdk.sh is executed, it needs the parameters: 
path/ld-linux-x86-64.so.2 path/dmesg.util-linux path/kill.util-linux 
path/reset.util-linux .....
The file list (path/dmesg.util-linux path/kill.util-linux 
path/reset.util-linux .....) is collected by "grep 
'\(executable\|dynamically linked\)'".

So "dynamically linked" is very import to the file ld-linux-x86-64.so.2. 
But in redhat 5.9(32 bit)

This file is as below:

ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped

In Ubuntu 12.04 (64bit)

This file is as below:

ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically 
linked, BuildID[sha1]=0xbb8c5184d8d41f31093193a2ec8d3f6f10964cd2, stripped

In this case, we can find in Ubuntu 12.04(64 bit), the flag "dynamically 
linked" is present, so ld-linux-x86-64.so.2 can be included in the file 
list. relocate_sdk.py can work according to the information from 
ld-linux-x86-64.so.2. But in redhat 5.9(32bit), the flag does not exist. 
relocate_sdk.py can not get the information from ld-linux-x86-64.so.2 
since this file is not included in the file list.

The same error occurs on redhat6.0(32 bit).

So the direct solution to this defect is to force this file 
ld-linux-x86-64.so.2 exist in file list.

If any problem, please feel free to let me know.

Best Regards!
Zhu Yanjun
