I had a look at the change you created and I'm not sure a flag to the
pkgbuild command is a good way to go.  I'm much more in favour of
simply making it the way we build, i.e. add
'--enable-executable-dynamic' on all builds of lib packages.

Sure, but I'm not convinced using shared libs is the route to take for
pure executable packages (like cblrepo and git-annex).  As long as
pure executable packages are linked statically we'll need the static
libs of course.  It's also the case that linking statically is the Ghc
default, which speaks in favour of keeping the static libs.
