I do not have the solution to your installation problem but I would just like to make a
suggestion for CC= when configuring for your mpc860 target.  Try CC="powerpc-linux-gcc
-mcpu=860" if the 860 is not your default processor when invoking gcc.  I think you can do
this at the configuration stage when building your cross-compiler or you can manually change
the specs file.
