Build: Fix out-of-tree build from tarball.

New description:

Bison is made a required dependency again. Also, dependencies for ly-grammar.txt are corrected.

Old description:

Build: Fix bison-less build from tarball.

A couple of fix to make dist:
  - Update bison-generated files timestamps.
  - Also include generated files in out-www dir.

Otherwise, these files are forced to be rebuilt, but bison
is supposed to be optional when building from the tarball.

Remove echo, leftover from debugging.

Fix out-of-tree build from tarball.

Basically, LGTM, but I might take a look at the German doc regarding the grammar
inclusion.  It would be preferable to be able to diss that.

$(outdir)/ly-grammar.txt
As mentioned in the comments: I don't think that contributor.texi depends on
ly-grammar.txt: it just has a @verbatiminclude of it inside.  So it should be
that whatever depends on contributor.texi would also depend on ly-grammar.txt.

Concretely: contributor.texi does not need to get rebuilt when touching
ly-grammar.txt.  I don't see a worse problem, though.

That gives us our own copy of ly-grammar.txt in the German documentation, right?
 Ugh.  Not fun.

Maybe we should push a quickfix for the German documentation first in order to
not even have to think about this one.

While that's technically true, my feeling is to go with the minimal change to
get the least surprises. Since this used to refer to notation.texi, I simply
changed it to notation.texi; this is easier to do than typing multiple
dependency rules for each output format, and avoids the risk of missing one.

right.

[Julien Rioux, 2013-10-01 12:08:08]

Remove additional dependencies in Documentation/de

The problem why this is creepier than the original rule is that notation.texi is
a generated file (from notation.tely) while contributor.texi is an original file
in our repository.

I am not sure how $(outdir) and VPATH and rules on the Makefile variable MANUALS
combine in that context.  At any rate, this would seem to warrant some thorough
testing to make sure that this works better than before.

$(outdir)/contributor.texi is a generated file (from contributor.texi; the rule
is a simple copy).
