General summary/comments (optional)

"stack hoogle generate --rebuild -- --local" gives "Packages missing documentation" for 'vector' package. This is a regression from Stack 1.4.0 to 1.5.0. The issue remains in 1.5.1.

Steps to reproduce

This was reproduced on Fedora 22 using downloaded stack binary ~/.local/bin/stack.

$ stack upgrade --binary-version 1.5.1 # Also repros with 1.5.0 but not with 1.4.0.
$ rm -rf ~/.stack
$ stack new --resolver=lts-9.1 doc
$ cd doc
$ vim doc.cabal # Add vector to the library build-depends
$ stack setup
$ stack haddock
$ stack hoogle generate --rebuild -- --local

The stack hoogle command complains about "Packages missing documentation" and 'vector' is one of the affected packages. There's nothing special about 'vector'. I'm just using it as an example of a package affected by this issue.

Expected

'vector' should not be one of the "packages missing documentation".
