- Remove a comment that was clearly copy pasted from Android.cmake and
isn't relevant.
- Remove the toolchain's sensitivity to the environment. It's less
error prone to just allow users to set CMAKE_OSX_SYSROOT if they
want to use a custom SDK.
- Stop explicitly setting -mios-version-min to the default value. It
just adds needless complexity.
This makes building the native tablegen work for me even when SDKROOT
is set in the environment (or passed in as -DCMAKE_OSX_SYSROOT).

* There is no reason to require SDKROOT as an environment variable because we can derive it from xcrun
* Setting CMAKE_RANLIB makes our static archives usable

The basic idea is similar to the existing cross compilation support. A directory must be configured to build host versions of tablegen tools and llvm-config. This directory can be user provided (and configured), or it can be created during the build. During a build the native build directory will be configured and built to supply the tablegen tools used during the build. A user could also explicitly provide the tablegen executables to run on the CMake command line.
