doc patch for dist-hook reference

[Karl Berry]

Pursuant to http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13324 ...

I suggest something like the following small change to the manual,
mentioning dist-hook instead of just unconditionally saying "don't use
directories in EXTRA_DIST".  Even though dist-hook is described the next
section, I for one read this text and never thought of going further :(.

        * automake.texi (Basics of Distribution): mention dist-hook
        as working around the problems of whole directories in EXTRA_DIST.
