generating tarstamp.h on trunk

["James K. Lowden" <jklowden@xxxxxxxxxxxxxxx>]

A few moments ago, I checked out the trunk, ran autoreconf and
configure, but could not compile because of a Makefile error.  

  $ svn checkout https://svn.code.sf.net/p/open-cobol/code/trunk trunk

The Makefile failed to generate tarstamp.h.  The message below is
reformatted for your reading convenience.  

libtool: compile:

	-I../../libcob \

../../libcob/common.c:23:22: fatal error: tarstamp.h: No such file or
directory compilation terminated.

The only code I could find that generates that file uses $(distdir),
which I don't think is right.  

I copied the tarstamp.h from a distributed tarball to the root of the
build tree, and was able to compile and link successfully.
