Bug#800846: error message in preinst doesn't match test, checks for kernel 3.2 but tells the user it needs 2.6.32

[peter green]

Package: libc6
Version: 2.21-0experimental1

I had an expermimental chroot on a system that happened to be running an 
old kernel. I got an error message about needing a 2.6.32 kernel which 
was strange as I already had a 2.6.32 kernel.

Reading the preinst revealed

        # The GNU libc requires a >= 3.2 kernel, found in wheezy
        if linux_compare_versions "$kernel_ver" lt 3.2
        then
            echo WARNING: this version of the GNU libc requires kernel 
version
            echo 2.6.32 or later.  Please upgrade your kernel before 
installing
            echo glibc.
            kernel26_help

            exit 1
        fi

So it's checking for 3.2 but telling the user they need 2.6.32.
