Comment:

 OK, it looks like this goes wrong because of the way we interleave the
 building of packages when building GHC. GHC assumes that if we're building
 one package, then packages that it depends on have already been built and
 are complete. Therefore, even if a module in the other package has a `.hs-
 boot` file, the real `.hs` file will also have been compiled and there
 will be a full `.hi` file.

 That seems like a reasonable assumption to make, and it doesn't look like
 anything actually fails as a result of this, so I don't think we need to
 take any action.
