This utility target will force a reconfigure of LLVM or your project. It + simply runs $(BUILD_OBJ_ROOT)/config.status --recheck to rerun the + configuration tests and rebuild the configured files. This isn't generally + useful as the makefiles will reconfigure themselves whenever its necessary. +
+This utility target, only available when $(BUILD_OBJ_ROOT) is not + the same as $(BUILD_SRC_ROOT), will completely clean the + $(BUILD_OBJ_ROOT) directoy by removing its content entirely and + reconfiguring the directory. This returns the $(BUILD_OBJ_ROOT) + directory to a completely fresh state. All content in the directory except + configured files and top-level makefiles will be lost. + Use with caution.
