Summary:                    CMAKE_OSX_SYSROOT and CMAKE_OSX_ARCHITECTURES
variables are actually clang-specific not osx-specific
Description: 
The CMAKE_OSX_SYSROOT and CMAKE_OSX_ARCHITECTURES flags are currently the best
supported way to set the -isysroot and -arch flags used by clang for
cross-compiling, but they only function fully if you are on Darwin. Clang
supports these flags on all platforms, so they should really be
CMAKE_CLANG_SYSROOT and CMAKE_CLANG_ARCHITECTURES.

Having platform-agnostic CMAKE_CLANG_ARCHITECTURES and CMAKE_CLANG_SYSROOT flags
would significantly improve cross-compiling support with clang. It would also
greatly help the LLVM project in our efforts to replace our autoconf build
system with CMake.
