incremental compilation of langtools does not work

[Erik Joelsson]

I've have a repro for this and created a bug (JDK-8007524). My change to 
javac/Main.java was visible when running jdk/bin/javac but not when 
running images/j2sdk-image/bin/javac, so the problem is in the 
dependencies for tools.jar.
