The require doesn't have to do with anything. bitbake emits only the
functions which get called somewhere from the task being run. It
tracks what variables reference what other variables. If you call a
shell function from another shell function, it tracks this, and
realizes that both need to be emitted. Either you're doing something
wrong, or you're doing something in a way that bitbake can't track.
There's a variable flag you can set to explicitly add variable
dependencies.
