[Haskell-iPhone] ld: warning with HEAD

[Maxwell Swadling]

Can you run arm-apple-darwin10-ghc  Blocks.hs -o Blocks.a ?

Also I'm not sure why you have a Main.a as well. You should link the Blocks.a in Xcode. You shouldn't need two .a's.

The config file was created by arm-apple-darwin10-cabal the first time I ran it. The build ends in two different ways depending on the `ghc-options` field in the Blocks.cabal file. With ghc-options: -staticlib -threaded it errors (or warns, or outputs - as it isn't specified):

Both static libs are ignored for each architecture and then clang ends in a linker error. Here is the build log from Xcode: http://lpaste.net/97304 and my setup: https://gist.github.com/schell/f3a737171ce2f6b1119c and the source: https://github.com/schell/blocks-ios/

That wiki page says nothing of using cabal so I'm assuming that I'm in dragon territory with most of this, so forgive me if I'm making some obvious mistake.
