Summary: make depend/clean issues w/ ast

Initial Comment:
I noticed two issues with the ast vis a vis building and
cleaning.  Haven't had a chance to look into them,
however...

1.  From a fresh checkout, execute configure, then
"make -j2".  It will run Parser/asdl_c.py twice
simultaneously.  This can obviously lead to
corrupt Python-ast.[ch] files.

2. Neither "make clean" nor "make distclean" delete
the Python-ast.[ch] files.  "make distclean" at least
should.

I was thinking it might be something like that.  Perhaps asdl_c.py
should be modified to accept an output flag (--output=[hc] or -h/-c)
so it only generates one file or the other.

The first problem is being caused by a simple
misunderstanding/oversight in Makefile.pre.in.

The rule for a target will be called for each target. In our
case, we have Python-ast.h and Python-ast.c in our list of
targets. So asdl_c.py gets called once for each target.

Hope this makes sense. :)

If not I can bang up a patch so you can at least see what
I'm on about.
