I think it should ideally complete the build in the current stage.
Not sure whether that's what your patch accomplishes.

This is nice, but depending on stage_last is a bit confusing,
especially given that it will not actually build everything all the
way to the last stage to only then start building the requested
library.  Any chance of changing the spelling of the dependency so
that its intuitive meaning matches the visible behavior?

Ok, thanks
