[PATCH FOR REVIEW]: Make source/target options explicit for JDK bootstrap tools

[Andrew John Hughes]

This is pretty much the same change as for CORBA, but for JDK:

http://cr.openjdk.java.net/~andrew/ecj/04/webrev.01/

BOOT_SOURCE_LANGUAGE_VERSION and BOOT_TARGET_CLASS_VERSION are added
and set to 6 by default.  They are then used by the bootstrap javac.
