添加2个make版本：
$ sudo update-alternatives --install /usr/bin/make make /usr/bin/make3.81 1010 
update-alternatives: using /usr/bin/make3.81 to provide /usr/bin/make (make) in auto mode

$ sudo update-alternatives --install /usr/bin/make make /usr/bin/make4.1 1011 
update-alternatives: using /usr/bin/make4.1 to provide /usr/bin/make (make) in auto mode

查看一下是否添加成功：
$ sudo update-alternatives --display make
make - auto mode
