This change has broken objcopy when padding has been added to the output 
section size. In my case, the output is binary format.

The bug causes a buffer read overrun which results in intermittent 
failures. It also looks like it will break byte reversal and interleaving.

The attached patch fixes the problem.

OK to commit?
