      If you have some pre-installed kernel headers lying around, you can
      enter the path to these headers, below, they will be copied from
      there, and into the toolchain's sysroot.
      
      Note:
      This will *not* let you use a complete kernel tree!
      If you want to use your own full kernel tree, then you want to say 'N'
      here, and select KERNEL_LINUX_CUSTOM, in the versions list, below.

      If you say 'n' here, the path above is expected to point to a directory
      containing readily prepared headers
      
      If you say 'y' here, then the path above is expected to point to a
      tarball of such a directory.
      
      Eg., if your headers are available in: /foo/bar/buz/my_hdrs/include,
      say 'n' here, and enter: /foo/bar/buz/my_hdrs below.
      
      Now, passing a tarball around is easier than passing a directory, so
      if you want to, you can make a tarball of /foo/bar/buz/my_hdrs/include,
      say 'y' here, and enter the path to this tarball below.
