Hi,

I did  and got the same output as you. But it seems like the script is 
not using the source tree path as in you asked me to do, rather it uses 
the output tree (after backport) path.
Looking into the Makefile is looks like the it checks if file named 
local-symbols exits (which not) and thus fails.

Thanks

Shetu.
