 This is the first in a series of patches for adding cross-compile ability
 for iOS.

 For now, 'arm-apple-darwin10' will be interpreted as iOS. Later we will
 need to tweak this to detect the difference between the iOS simulator
 (with an i386 cpu) and the native Mac.

 I am creating a new logical OS name 'ios' because the differences between
 iOS and Mac can be quite significant. I thought it would we best not to
 introduce the idea of an OS variant (as we did with ARM cpus) for two
 reasons: 1. it's over-complicating the issue and 2. it would require some
 modification of cabal.

 Versioning: I'm submitting patch version 1a here. If I have to revise a
 patch, I'll bump the letter.
