I just started seeing this, with "make -j4":

There is indeed no rule to make classpath/lib/compile-classes, as it's
generated in a recursive sub-make (which would happen earlier in a
non-parallel build, or at lower -j levels, rather than simultaneously and
racily as here). Presumably we need to add some dependency at the top level,
perhaps something like this?
classpath/lib/compile-classes: all-multi
