[Haskell-cafe] GHC iOS ARMv7/ARMv7s fat support completed

Hi folks, Happy to report that I've finished an approach to armv7/armv7s fat compilation, just in time for 7.8's imminent release. You'll find the necessary scripts here: https://github.com/ghc-ios/ghc-ios-scripts and the latest instructions for building GHC for iOS usage here: https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS I've also added support for a perf-cross BuildFlavour, which will give a higher-performance and profiling-ready build that matches what we'll be putting together as the official 7.8 GHC iOS binaries: https://ghc.haskell.org/trac/ghc/ticket/8700 Cheers Luke
