That used to be true, but it is no longer necessary to install the
toolchain in the same place as --prefix. The compiler driver figures
out its own location and then uses relative paths, as well as absolute
paths like the prefix.

I suggest checking the access rights on cpp0 to make sure you haven't
lost the execute bit somehow. If that does not work you can try
running strace on a powerpc-eabi-g++ invocation to see what it is
actually trying to do.
