JDK libraries build question: propagating a new make variable/value

[Brad Wetmore]

Many of the common variables used throughout JDK are defined in the 
common and shared Makefiles, and then included in the various leaf and 
middle makefiles.  I'd start by looking at those first.  Another tip, 
many of the common Makefiles include other common Makefiles, so if one 
you need isn't listed, it's very possible that it's referenced by 
another one that is.  It can take a while to unravel what's included 
just by including one top level Makefile.

HTH,

Brad
