The setting build.proj.ref.configs.enabled=true ensures CDT projects are
not rebuilt if non-related projects are changed. This setting cannot be
changed with product or command line customization, hindering products
which require this behavior.
The reason for this is that ACBuilder, which is asked for the value of
the preference, communicates with the instance scope of preferences.
Product and command line customization, however, are on default scope
level.
With this change, ACBuilder will also ask the default scope when
retrieving the value of the preference.
