Trigger the generation of file scripts/Module.ksymb in Makefile by calling updated scripts/streamline_config.pl with corresponding parameter (--genmodulesymb). The file is generated at each compilation considering that associations may change after tree updates.
This patch is part of a research project within Google Summer of Code of porting 'make localmodconfig' for backported drivers. The goal is to enable each module to expose in /sys its corresponding CONFIG_* option. The value of this attribute will be dynamically pegged by modpost without requiring extra work from the driver developers. Further, this information will be used by a hardware interogation tool to extract build information about the existing devices.
