Subject: [PATCH 10/11] Fixing make distcheck

* doc/docs.mk: (a) adding a license header; (b) removing a double entry
  in clean-docs target; (c) adding DISTCLEANFILES; (d) removing
  $(doc)scmfiles (it was not actually used anywhere); (e) removing
  $(doc)depfiles target, instead declare 'depfiles' as a toplevel
  variable.

  Notes: (1) wrt to (e), it was the only (unportable) way I found to
  have 'make ditcheck' work. The problem of having $(depfiles) as the
  result of a target is, because the documentation is generated (there
  is no guile-library.texi files in the distribution), and due to
  both (a) the way automake determines which files must be
  generated (timestamp), IIUC, and (b) the fact that file generation
  occurs in $(builddir), all this, unconditionally leaded to a texinfo
  [and dvi, pdf, ...) error, since in the $(buiddir), none of the
  guile-library.texi dependency files (fdl and NamesConventions)
  exist. Leaving things as they were ans using TEXINFO := $(TEXINFO) -I
  ../../../doc would not work either, because that triggers an attempt
  to write in $(scrdir), which is prohibited;

  (2) this solution is unportable (it depends on GNU Make), but this is
  not the first, guile-lib already used $(addprefix), so I guess with
  this respect my patch is ok.  Of course if someone else has/knows a
  better solution, I'm all hears, ping me!

  (3) A special thank here to Colomban Wendling, aka b4n, who spent a
  couple of hours with me on irc, #autotool, to track this issue down, to
  finally conclude that, in his opinion and within the scope of his
  knowledge, there would be no way to solve this using targets.
