the powerpc-linux-gcc in ELDK was built with hard-coded sysroot
which is:
$ powerpc-linux-gcc -print-sysroot
/opt/eldk-5.5.2/powerpc/sysroots/powerpc-linux

If the ELDK-5.5.2 wasn't installed in the default location
/opt/eldk-5.5.2, then the real sysroot should be specified
to powerpc-linux-gcc by the --sysroot option. This will be
done by setting CC when you source the environment setting
script for the toolchain, e.g.:

 $ source ~/development/ELDK/powerpc/environment-setup-powerpc-linux
 $ unset LDFLAGS

Then the building should work by running

 $ make CC="$CC"

Thanks,

Anatolij
