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.
