BUG: Updated Makefile dependency scanning to provide a full local generator to the dependency scanner to do proper path conversions. This allows the rules written into the depend.make files to use the same relative path conversion as those written into the build.make files. Several previous changes added more and more information for use by the dependency scanner and it was converging to having the full local generator anyway.
