Currently, $(objtree)/modules.order is touched in two places. In the 'prepare0' rule, scripts/Makefile.build creates an empty modules.order while processing 'obj=.' In the 'modules' rule, the top-level Makefile overwrites it with the correct list of modules. It might be a good side-effect that modules.order is made empty every time (probably this is not intended functionality), but I personally do not like this behavior. Kbuild descends into some directories in the preparation stage, where created modules.order files may be broken. Export 'preparing' while running the 'prepare' target, and when it is defined, do not touch modules.order at all.
