Use the kernel-source folder name to hide the kernel version path, and this folder will be created as symlink. Before building kernel, the script will build the symlink based on the kernel version of environment variable. The advantage of this is that there is no need to change the path whenever the version is updated, and the build can be switched between different kernel version.
