One way to export the values of the feature configurations to the build system  it is to run the preprocessor on the header file with all the same build flags that the build system would otherwise use (e.g. to establish the port). 

This technique is already used in WebCore/DerivedSources.make (check how the defaults for ENABLE_DASHBOARD_SUPPORT and for ENABLE_ORIENTATION_EVENTS are set).

This is just a potential and the risks needs to be discussed with the benefits.
