Re: relocate_sdk.py: Possible bug, /lib64/ld-linux-x86-64.so.2 not relocated

Hi Stefan,

Can you please have a look at the binaries before relocation? Just to
make sure...

So, for that, run the installer with -R option:

./your_toolchain_installer.sh -R

Here, I'm interested which is the default suggested path (see below):

Enter target directory for SDK (default: /opt/poky/1.5+snapshot):

Then, run 'readelf -p ".interp"' on those binaries. They should all start
with the "default" prefix.
