 If you are installing the GNU C Library on GNU/Linux systems, you need
 to have the header files from a 3.2 or newer kernel around for
-reference.  These headers must be installed using 'make
-headers_install'; the headers present in the kernel source directory are
-not suitable for direct use by the GNU C Library.  You do not need to
-use that kernel, just have its headers installed where the GNU C Library
-can access them, referred to here as INSTALL-DIRECTORY.  The easiest way
-to do this is to unpack it in a directory such as
-'/usr/src/linux-VERSION'.  In that directory, run 'make headers_install

 the most recent kernel you can get your hands on.  (If you are
