create a file called "dontdiff"
which contains lines like
*~
*.a
*.o
*.orig
*.rej
*.ver
*.bin

And any other shell patterns you DONT want included in your patch.

Then
diff -urN -X dontdiff archive-copy new-code > /tmp/patch

That create your patch but it will exclude the files that match dontdiff

You may find it is usefull to do a a make clean before running the diff also.
Or create a special make target that just takes out the executables.

Cant really help with this second option BUT using the nice features of diff
you should be able to get what you need.

I mean it works for the kernel so I'm sure you can get it going for your code.
