    kbuild: modpost: do not parse unnecessary rules for vmlinux modpost · a721588d

    Since commit ff9b45c5 ("kbuild: modpost: read modules.order instead
    of $(MODVERDIR)/*.mod"), 'make vmlinux' emits a warning, like this:
    
    $ make defconfig vmlinux
      [ snip ]
      LD      vmlinux.o
    cat: modules.order: No such file or directory
      MODPOST vmlinux.o
      MODINFO modules.builtin.modinfo
      KSYM    .tmp_kallsyms1.o
      KSYM    .tmp_kallsyms2.o
      LD      vmlinux
      SORTEX  vmlinux
      SYSMAP  System.map
    
    When building only vmlinux, KBUILD_MODULES is not set. Hence, the
    modules.order is not generated. For the vmlinux modpost, it is not
    necessary at all.
    
    Separate scripts/Makefile.modpost for the vmlinux/modules stages.
    This works more efficiently because the vmlinux modpost does not
    need to include .*.cmd files.
    
    Fixes: ff9b45c5 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod")
