make install arch/x86/Makefile:245 中出错：*** 您正在使用非 retpoline 编译器构建内核，请更新您的编译器。停止

Question

我一直在尝试按照此网站上给出的步骤操作 http://ubuntuhandbook.org/index.php/2018/08/no-wifi-adapter-found-hp-laptops-ubuntu-18-04/ 在我的 HP 笔记本电脑上安装 WiFi 适配器设备驱动程序。但是当我使用该 sudo make install 命令时，我收到错误

make -C /lib/modules/4.15.0-50-generic/build M=/home/keith/rtlwifi_new modules
make[1]: Entering directory '/usr/src/linux-headers-4.15.0-50-generic'
arch/x86/Makefile:156: CONFIG_X86_X32 enabled but no binutils support
arch/x86/Makefile:245: *** You are building kernel with non-retpoline compiler, please update your compiler..  Stop.
make[1]: Leaving directory '/usr/src/linux-headers-4.15.0-50-generic'
Makefile:87: recipe for target 'all' failed
make: *** [all] Error 2

我也尝试使用命令

sudo make clean
sudo make 

结果：

make -C /lib/modules/4.15.0-50-generic/build M=/home/keith/rtlwifi_new modules
make[1]: Entering directory '/usr/src/linux-headers-4.15.0-50-generic'
arch/x86/Makefile:156: CONFIG_X86_X32 enabled but no binutils support
arch/x86/Makefile:245: *** You are building kernel with non-retpoline compiler, please update your compiler..  Stop.
make[1]: Leaving directory '/usr/src/linux-headers-4.15.0-50-generic'
Makefile:87: recipe for target 'all' failed
make: *** [all] Error 2

我该怎么做才能修复这个 make 错误？
