Build fails with internal libraries that aren't dependencies

[KaneTW]

Test case: https://github.com/KaneTW/stack-internal-lib-bug

cabal new-build succeeds.

There seems to be an issue with dependency resolution. Specifically, sublibs don't count as dependencies that have to be built.

Adding a dependency on every internal lib is a workaround.

Thanks for the report. I was able to reproduce and I'll try to get a fix.

Solved in #4033

Tested here. At first it failed (ie, no change) but it seemed to be using precompiled (thus buggy?) haddock-library artifacts. I manually nuked anything by that name in ~/.stack with find ~/stack -name 'haddock-library-*' -type d -print0 | xargs -0 rm --dontcopyandpastethis (which I'm sure was overkill) and although stack build works it is still failing for stack haddock.

Please re-open?

There seems to be another bug regarding pre-existing artifacts. Will test that too and open an issue.

I haven't yet managed to get to stack haddock, it's in the plan for this week.
