关于内核配置和编译的问题，求助！

1、通过make menuconfig后生成了.config文件，
2、预期的结果应该是正常编译内核源码，但是执行make uImage时还会提示我配置内核选项，形如：

1.   45. Samsung S5P6442 (ARCH_S5P6442) (NEW)
   
2.   46. Samsung S5PC100 (ARCH_S5PC100) (NEW)
   
3.   47. Samsung S5PV210/S5PC110 (ARCH_S5PV210) (NEW)
   
4.   48. Samsung S5PV310/S5PC210 (ARCH_S5PV310) (NEW)
   
5.   49. Shark (ARCH_SHARK) (NEW)

13.   57. ST SPEAr (PLAT_SPEAR) (NEW)
    
14. choice[1-57]: 56

我看了这时的make uImage输出，打印了

1. scripts/kconfig/conf --silentoldconfig Kconfig

复制代码

同时Makefile里关于这段的说明是：

1. ifeq ($(KBUILD_EXTMOD),)
   
2. # Read in dependencies to all Kconfig* files, make sure to run
   
3. # oldconfig if changes are detected.
   
4. -include include/config/auto.conf.cmd
   
5. 
   
6. # To avoid any implicit rule to kick in, define an empty command
   
7. $(KCONFIG_CONFIG) include/config/auto.conf.cmd: ;
   
8. 
   
9. # If .config is newer than include/config/auto.conf, someone tinkered
   
10. # with it and forgot to run make oldconfig.
    
11. # if auto.conf.cmd is missing then we are probably in a cleaned tree so
    
12. # we execute the config step to be sure to catch updated Kconfig files
    
13. include/config/%.conf: $(KCONFIG_CONFIG) include/config/auto.conf.cmd
    
14.         $(Q)$(MAKE) -f $(srctree)/Makefile silentoldconfig

我对这段说明不是很理解，请教下大家是什么原因会导致这样？
