Remind me why you need --print-libdir again?  I have a feeling that this
information should be private to GHC.  Oh, is it because the package
specs contain the string "$libdir"?

Anyway, to get access to the Haddock interfaces and HTML docs, we've
been thinking that this information ought to be in the package specs.
And we're revamping this design at the moment as part of the library
infrastructure project... stay tuned (the draft design will be publish
in a matter of days).
