Previously, the user could only compile using the default version of
GHC in Nixpkgs. Now this can be changed by setting the `ghc` attribute
appropriately.
The function "callHackage <name> <version>" generates build instructions for
the requested library version on-the-fly. All of Hackage is available. Note:
this code is brand-new, experimental, and it might change in the future. Don't
base production code on this feature yet.
Example usage:
$ nix-shell -p 'haskellPackages.callHackage "cpphs" "1.19.3" {}' --run "cpphs --version"
cpphs 1.19.3
$ nix-shell -p 'haskellPackages.ghcWithPackages (self: [(self.callHackage "hsdns" "1.6.1" {})])' --run "ghc-pkg list hsdns"
/nix/store/p6r81k2vb2pzy4wcvri6z9m492i0hg63-ghc-8.0.1/lib/ghc-8.0.1/package.conf.d
hsdns-1.6.1

Now we're releasing incomplete Hackage tarballs on purpose:

You know, I'll fix this shit one last time, but on the next occasion
upstream breaks the build for no apparent reason, I'm going to abandon
this project and leave it to someone else to package, because these kind
of wacko engineering decisions cast a bad light on the soundness of
git-annex as a whole, IMHO.

These overrides didn't work, because they created a mixture of different
versions of 'persistent' in the build tree. Furthermore, we cannot pin
specific versions like that in configuration-common.nix because this
breaks builds in other package sets, i.e. the LTS variants.

A change in the way the gtk2hs libraries make use of gtk2hs-buildtools
caused them to move the dependency into a stanza where cabal2nix doesn't
pick it up---so we need to do these by hand for the moment.
