This is bad, I agree. We initially kept the same variable for 
controlling if the build was OpenJDK only or not as the old build, 
because it made it easier during the conversion. The problem with this 
variable is that it is either set or not, which makes it harder to 
override in makefiles. The proper solution would be to replace this in 
the new build with something like OPENJDK_ONLY=true/false and completely 
ignore the old OPENJDK.

I can't remember any other variables right now, but it's quite possible 
there are more.
