The package manager `opkg` offers the function `whatdepends` to print
packages that depend on a specific package.
This feature is useful when used in a CI to not only build an upgraded
package but all packages with a dependency.
Usage:
make whatdepends PACKAGE=libipset
The resulting list can be fed into a SDK building all packages and warn
if anything fails.
