Of course not. I just wanted inform that -pie is not working.
Actually I don't know how to fix it correctly. It's may be interesting 
for more people, especially who wrote relocation code.
At least one person except me in this list faced the same problem.
Maybe somebody could do test with different compiler/binutils versions 
and figure out whether is it depended or not. I have only single ARM 
toolchain and can't do such test yet.
