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.

I'm currently running a CI which determines affected areas as first
step, an example is here where the `fstools` packages was modified:
https://gitlab.com/aparcar/openwrt/-/jobs/696713593#L48
With the whatdepends extension it would be possible to figure out all
affected packages.
