I've done rewriting dpkg-cross -b procedure using different logic.
Now it first completely unpacks the spirce deb, and then analyses it's
contents. Analysis logic is documented in comments in the code.
New procedure is tested on a set of about 100 packages: I've converted
those using old and new dpkg-cross, and manually checked the difference.
Everything seems to be correct.
I've commited fix to CVS on alioth, and also updated dpkg-cross package in
my repository to 1.14.7
