Add support for "platform" configurations, which define a suite of compiler-rt libraries to generate. - Each library may be built with different flags and for different architectures, and there is support for building Darwin style fat archives. - Uses an ambituous amount of make programming, but should be hidden to users and developers. llvm-svn: 93720
