Update dependencies
Merge branch 'master' of http://darcs.haskell.org/git-mirrors/Cabal/
Follow unix's version bump
Add iOS as an OS.
Add 'compilerTargetPlatform' to Compiler data type, which is inferred from ghc --info using new 'platformFromTriple' function. Falls back to old behavior of buildPlatform when the target platform can't be inferred.
Thread compilerTargetPlatform through to initialPathTemplateEnv
Adds $arch-$os to libsubdir, datasubdir and docdir by default as suggested in https://github.com/haskell/cabal/issues/1184#issuecomment-12450398
