Fixed `make -jN depend' (N >= 2) by removing the beforedepend target.  .ORDER doesn't work right, but is used for things related to the depend target.  It "works" for the depend target by skipping the build of .depend when N >= 2 and there is a non-default beforedepend target with no rules.  Recent fixes made almost all the beforedepend targets in the tree a no-op except for this bug.
