If you log into the OPAC as a user with no flags, you can see a restricted view of
/cgi-bin/koha/tools/tools-home.pl instead of seeing the login screen.

Test plan:
Use a patron with catalogue permission only
Login and access the tools home page
=> redirected to the login screen

Add a club sub permission
Login and access the tools home page
=> You see the tools home page with the clubs link

Add a tool sub permission, remove club
Login and access the tools home page
=> You see the tools home page with the relevant link
