[yocto] [prelink-cross] error while loading shared libraries: ld-linux.so.3

I tried to move the files to their location in sysroot:

arm-2012.03/arm-none-linux-gnueabi/libc/usr/local/include/world.h
arm-2012.03/arm-none-linux-gnueabi/libc/usr/local/lib/libworld.so
arm-2012.03/arm-none-linux-gnueabi/libc/usr/local/bin/hello
arm-2012.03/arm-none-linux-gnueabi/libc/etc/prelink.conf


> What command did you use to run the prelinker?  And does your sysroot

prelink command:

PATH=/usr/local/sbin prelink --verbose
--root=arm-2012.03/arm-none-linux-gnueabi/libc
--cache-file=/etc/cache/prelink.cache --config-file=/etc/prelink.conf
--ld-library-path="/usr/local/lib;/lib;/usr/lib;" -h /usr/local/bin/hello


error message:

prelink.conf

-l /lib
-h /lib
-l /usr/lib
-h /usr/lib
-l /usr/local/lib
-h /usr/local/lib


Now there is no error message from rtld and libworld.so seems to be found.
But what's the problem with the folling libraries?

libdl-2.15.so
libc-2.15.so
libgcc_s.so.1
ld-2.15.so


I can see them in this folder arm-2012.03/arm-none-linux-gnueabi/libc/lib:

-rwxr-xr-x 1 developer users  177212 10. Jun 18:43 ld-2.15.so

lrwxrwxrwx 1 developer users      13 10. Jun 18:43 libld-linux.so.3 ->
ld-linux.so.3



I have also put the code on github for reference. Where is the mistake? - I
think we are almost there :-)
