clang: Initial 3.2 port

* TODO: clang seems to install a lot of stuff
  where it shouldn't (ignoring manDir, docDir, etc)
* Marking build arch as ? for now until above
  is solved

+SUMMARY="A llvm front end compiler for C and C++" 
+DESCRIPTION="Clang is an 'LLVM native' C/C++/Objective-C compiler, which
+	aims to deliver amazingly fast compiles (e.g. about 3x faster than
+	GCC when compiling Objective-C code in a debug configuration),
+	extremely useful error and warning messages and to provide a
+	platform for building great source level tools."
