The changes are now in master, too:
commit d64917ad17277b8e16893ee31533ec2e33446fa7

Back-port Haskell-related improvements from stdenv-updates.
* There now is full support for building Haskell packages as shared
libraries
for GHC versions 7.4.2 or later. The Cabal builder recognizes the
following
attributes:
- enableSharedLibraries configures Cabal to build of shared libraries in
addition to static ones. This option requires that all dependencies of
the package have been compiled for use in shared libraries, too.
- enableSharedExecutables configures Cabal to prefer shared libraries
when
linking executables.
The default values for these attributes are arguments to the
haskellPackages
expression.
* Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid
plenty
of build and test suite errors. Without this setting, GHC seems unable to
deal with the UTF-8 character encoding that's generally considered
standard
in the Haskell world.
* The Cabal builder supports a new attribute 'testTarget' to specify the
exact
set of tests to be run during the check phase.
* The ghc-wrapper attribute ghcVersion has been removed. Instead, we use
the
ghc.version attribute, which exists in unwrapped GHC derivations, too.
