+ <p>This utility target will force a reconfigure of LLVM or your project. It
+ simply runs <tt>$(BUILD_OBJ_ROOT)/config.status --recheck</tt> to rerun the
+ configuration tests and rebuild the configured files. This isn't generally
+ useful as the makefiles will reconfigure themselves whenever its necessary.
