Details:

Inspired by a discussion of reproducible builds in Debian (see
https://wiki.debian.org/ReproducibleBuilds), I've looked for and found a few
places in the Octave build system that intentionally encodes variable
information into the build output that depends on time stamps, file paths, and
host-specific information. From a reproducible build perspective, these should
all be removed so that given the same original source, the same result comes
out each time.

Some easy pickings:
* config.log - so bad, why is this now being installed in >= 3.8.1?
* doc-cache - fix the header to just say "created by Octave VERSION" without
any timestamp

Some further/harder changes:
* Timestamps are stored in PDF and PS versions of the manuals
* Timestamps are stored in doc-cache files created when pkgs are installed,
could be solved in pkg similarly to Octave's doc-cache above

There may be others, but these are the obvious ones I've found so far.
