make: *** [vmlinux] Error 1
-------------------------------
在内核配置时做改变,希望支持FRAMEBUFFER：
1  在char devices 里增加支持
    virtual terminal
    support for console on virtual terminal (选或不选都出错)       
2  在console drivers 里增加如下支持：
   virtual frame buffer support
--------------------------------
导致错误的原因请指点，是不是还有哪里没有选择啊？才导致函数间的依赖出错。
第一次添加frambuffer时估计都会遇到这个问题，谁知道哪里的问题？

那你得看这些undefined reference 的 函数或变量到底是在什么地方定义以及实现的. 具体再做调整.
