Build problems regarding missing README.html

Already reviewed... but just for the record...

6843925: Fix broken images target, no README.html file found, wrong source dir for files

http://cr.openjdk.java.net/~ohair/jdk6/6843925-LICENSE/webrev/

This change is on it's way, being test built now.

FYI...

The jdk6 (OpenJDK6) Makefiles still have the concept of OPENJDK=false
or the idea of building a Sun JDK, this logic is not being used but
in general it is left in the makefiles to better match up with jdk7
makefiles.
