Which prelink are you using, it's possible you did not look at the 
correct one.

There should be a tmp/sysroot/x86_64-linux/usr/sbin/prelink (if you are 
building on a 64bit machine, otherwise i586-linux), that's the prelink 
binary and a --help to that will show the --root option.

It should not be using your host's /etc/prelink.conf, but the sysroot 
version.

The --root option should take care of it as it's described as follows:

      --root=ROOT_PATH       Prefix all paths with ROOT_PATH

So, the next question is what's going on to cause it to use your host's 
prelinker instead of the native version that should be build as part of 
the native tools?
