Tue Nov 25 15:56:33 UTC 2014

This is a bag of fixes that has been developed in the build-infra forest 
as part of preparatory work for converting the hotspot repo and closed 
Oracle repos to the new build-infra structure.

The fix includes:
    * Setup proper dependencies for Windows RC files (.res)
    * Make it easier to support new types of native files and new 
extensions
    * Improved support for Objective-C
    * Additional arguments for customization
    * Improved logging
