How to Pass Javac Option in the New Build

[Erik Joelsson]

I don't believe this has been properly addressed yet, but there are a 
couple of ways to change the flags to javac that work now. Note that 
these variables might change and we aren't officially declaring this as 
a supported method.

JAVAC_FLAGS is added to all javac command lines. It's defined in 
spec.gmk (by configure) but is currently empty and setting it on the 
command line should override.

DISABLE_WARNINGS is set in jdk/makefiles/Setup.gmk and defines a long 
-Xlint parameter disabling most (if not all) warnings. Overriding it 
would be a first step towards enabling warnings in the jdk repo.

Both of these need to be on the command line to be overridden.
