Right -- actually need to avoid defining the symbols at all (such as
removing ERR77 from the CONFIG_SYCAMORE case) since an "ifdef" check is
used (that should probably be fixed as well).  We've just run the same
kernel binary on 405GP "Walnut" and 405GPr "Sycamore" boards, so haven't
been cleaning up the 405GPr specifics.
