I agree that page is very bad at communicating the information it needs 
to communicate.  Perhaps it would be much more helpful if it had a few 
examples of .cygport files rather than diving into the minutiae of 
setup.hint files.

However, I took a look over it, but I don't see what needs updating for 
this particular change.  Can you be more specific about what you think 
needs updating?

I have updated https://sourceware.org/cygwin-apps/package-upload.html

That didn't actually explain before what to do if you are manually 
uploading a noarch package ("if you are doing a manual upload, and your 
package is noarch, you'll need to upload to both x86 and x86_64"), so 
I'm not sure how to update it for the hopefully more straightforward 
present situation ("if you are doing a manual upload, and your package 
is noarch, upload to noarch").
