I accidentally removed a bunch of links in a previous change,
that isn't pushed yet.
due to gitignore rules, files in config/submodule/ have to be
added manually using -f with the git add command. as a result,
i need to be very careful when making changes, especially
temporary changes.
lbmk wasn't downloading files properly, because upstreams weren't
defined. this patch fixes that.
