(cherry picked from commit 5c82c9fc)

This makes the GHC build-system aware of the data-files to be copied
into the bindist (as haddock.cabal doesn't list those anymore)

Changed copy of utils/haddock/html/resources/html to use "cp -RL" rather than "cp -R". This allows users to run validate in a build tree, where the build tree was setup using lndir with a relative path to the source directory.

"7.0.2" looked like a haddock version number before

In particular, it now doesn't get created if we aren't installing
haddock.

Data-files are now in subdirectories, so we need to handle that
