Doc building for ios

Compilation currently does not link, see #10384.

You need XCode 5.

1. Build Rust:

mkdir build; cd build
../configure --target=arm-apple-darwin
make VERBOSE=1

1. Use Rust:

rustc --target=arm-apple-darwin foo.rs

Possible adjustments

• Compilation:
  • Compile twice, with both -arch armv7 and -arch armv7s (A6 processor) ?
    • See https://github.com/ghc-ios/ghc-ios-scripts/blob/master/arm-apple-darwin10-clang
• Code:
  • src/librustc/back/arm.rs
  • src/rt/arch/arm/record_sp.S
