准备使用 stm32l4r5-st-nucleo BSP 在 L4R5-NUCLEO 板子上跑起来，进入 stm32l4r5-st-nucleo 执行 scons 是Ok的。但是 menuconfig 之后再 scons 就有问题了 :(

提示“...... libraries\STM32L4xx_HAL\CMSIS\Device\ST\STM32L4xx\Source\Templates\gcc/startup_stm32l4r5xx.s:98: undefined reference to `entry'”

对比前后两个 .config 文件，发现少了点东西 :o

**Before >>**

```#
# RT-Thread Components
#
CONFIG_RT_USING_COMPONENTS_INIT=y
CONFIG_RT_USING_USER_MAIN=y
CONFIG_RT_MAIN_THREAD_STACK_SIZE=2048
CONFIG_RT_MAIN_THREAD_PRIORITY=10```

**After >>**

```#
# RT-Thread Components
#
# CONFIG_RT_USING_COMPONENTS_INIT is not set
# CONFIG_RT_USING_USER_MAIN is not set```

然而，我想手动加回去，却发现 RT-Thread Components 选项里面没有这两项 :L

rt-thread/components/Kconfig 里面明明是有的啊。。。
```menu "RT-Thread Components"

config RT_USING_COMPONENTS_INIT
    bool 
    default n
    
config RT_USING_USER_MAIN
    bool 
    default n
    
    if RT_USING_USER_MAIN
        config RT_MAIN_THREAD_STACK_SIZE
            int "Set main thread stack size"
            default 2048
        config RT_MAIN_THREAD_PRIORITY
            int "Set main thread priority" 
            default 4  if RT_THREAD_PRIORITY_8
            default 10  if RT_THREAD_PRIORITY_32
            default 85  if RT_THREAD_PRIORITY_256
    endif
```

求大神路过指点 :)
