[directory-discuss] Non-GNU software links to the FSD main page

[David Hedlund]

I suggest that we add this to https://directory.fsf.org/wiki/:

For software only available on non-GNU/Linux operating systems see: 
[https://www.gnu.org/software/for-windows.en.html Free Software for 
Windows], [https://www.gnu.org/software/for-ios.en.html Free Software 
for iOS], [https://www. f-droid.org] for android apps (proprietary 
software is warned about).
