    kbuild: do not create empty modules.order in the prepare stage · 7e131918
    Masahiro Yamada authored
    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.
    
    While this might be a good side-effect that modules.order is made
    empty every time (probably this is not intended functionality),
    I personally do not like this behavior.
    
    Create modules.order only when it is sensible to do so.
    
    This avoids creating the following pointless files:
    
      scripts/basic/modules.order
      scripts/dtc/modules.order
      scripts/gcc-plugins/modules.order
      scripts/genksyms/modules.order
      scripts/mod/modules.order
      scripts/modules.order
      scripts/selinux/genheaders/modules.order
      scripts/selinux/mdp/modules.order
      scripts/selinux/modules.order
    
    Going forward, $(objtree)/modules.order lists the modules that
    was built in the last successful build.
