Hi!
 I think there is still a "bug" I corrected:
You keep getting the name of the dynamic linker from the PT_INTERP 
program segment, but that gives you the absolute position of the dynamic 
linker inside the machine the target binary was created in.
Here qemu-user is an emultaor used for running that binary into another 
machine..
Qemu default to usr/gnemul/ the path where the libs for the target 
machines are stored...
So we need to patch the absolute dynamic linker name with the proper path..
I dunno maybe this can be my first little contribute to qemu family ;)
