[PATCH] don't keep a gdb-specific date

[Tom Tromey <tromey at redhat dot com>]

Right now there are two nightly commits to update a file in the tree
with the current date.  One commit is for BFD, one is for gdb.

It seems unnecessary to me to do this twice.  We can make do with a
single such commit.

This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfdver.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.

I remove the cron job that updates the version on trunk, and then
check in this patch.

For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h.  I believe this is a simple change in the
crontab -- the script will work just fine on this file.
