cross-install's dpkg dependency

[Daniel Burrows <Daniel_Burrows@brown.edu>]

  It occured recently to me that requiring dpkg to be installed for the .deb
installation method of the Hurd is a nuisance for a significant number of
people (as evidenced by periodic postings to this list)  Since the cross-install
scripts only use dpkg as a simple archive extractor, it seems like we should
be able to replace it with calls to ar, tar, and gzip by fiddling with
dpkg-hurd a little bit.  I looked over the script and it looks quite doable,
probably the work of a few hours at most.  Does anyone know of any reason
that this wouldn't be possible?  If not, I may look into it this evening..
