无法编译内核：错误，内核不支持 PIC 模式

Question

我在重新编译内核时遇到了麻烦。下载源码包，解压运行

fakeroot make-kpkg kernel_image  

导致我出错

               [...]

  CHK     include/generated/utsrelease.h
  UPD     include/generated/utsrelease.h
  CHK     include/generated/package.h
  UPD     include/generated/package.h
  CC      kernel/bounds.s
kernel/bounds.c:1:0: error: code model kernel does not support PIC mode

该问题可以通过更改使用 获得的内核配置来解决make menuconfig。

如何摆脱这个错误并成功编译
