Title: Altered the build system to better accommodate building on Mac OS X.

Checks to see if Xcode command line tools are installed and if not uses xcrun to run relevant commands. Gives indication which Xcode package is selected using xcode-select. Asks which SDK should be used to build against. Asks which architecture should be used to build.
