I added --with-vm-classes to solve this problem for the
classpath-in-libgcj build.  Basically by default we use the stuff in
vm/reference, but --with-vm-classes completely overrides this.  Then,
in addition, the "enclosing" build can override specific files (eg
String.java) with its own versions.

This is pretty much completely ad hoc, but, say, if kaffe were to
switch to this build model it ought to work fine there as well.  Hint,
hint.
