PATCH: maintainer-scripts/gcc_release

[Gerald Pfeifer <gerald at pfeifer dot com>]

This has generated the last four (or so) snapshots, both off mainline and
the 3.3-branch without problems.

As far as I can see, this will now fail for prereleases, but this is less
due to my change but to actual problems of prereleases not being
reproducible (in a simple way), and I plan to address it in a more general
way in the near future.  Apart from that, it seems I'm done with my rework
of that script. :-)

Installed.

 	* gcc_release (build_sources): Use two new variables EXPORTTAG and
 	EXPORTDATE to make the extraction of sources more transparent and
 	also allow snapshots (off mainline) without a tag.
