[haskell-llvm] pushing llvm-base with patched setup.hs to hackage

[Carter Schonwald]

if you need hugs support, please give us a patch that is of that cpp style
I've outlined that you've tested locally, as I and others don't have access
to hugs and i'm happy to help merge it in.

In the mean time, I think making sure that llvm bindings work on all
current and near future haskell platform releases takes priority over
aesthetical arguments against so.


With that out of the way, any objections to me pushing a minor version bump
so that the the llvm and llvm-base will work with more cabals?
