JDK 9 RFR of changing sense of lint warning in the jdk makefile

[Joe Darcy]

Hello,

In the makefile for the jdk repo, the current options list to javac's 
warning is a bit awkward since it lists all the options that are enabled 
as opposed to the ones which are disabled. Nearly all the options are 
enabled now (yay!) and I think it would be cleaner to reverse the sense 
of the list:

  # Any java code executed during a JDK build to build other parts of 
the JDK must be
  # executed by the bootstrap JDK (probably with -Xbootclasspath/p: ) 
and for this

If there is agreement this is an improvement, I'll file a bug and have 
the change pushed via jprt. (This change works for an OpenJDK build on 
linux, but there is a possibility closed or platform-specific code 
triggers some warning not related to source code, like options handling, 
in which case a few additional "-foo" clauses might be needed.)

Thanks,
