kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang
Add support to toplevel Makefile for compiling with clang, both for HOSTCC and CC. Use cc-option to prevent gcc option from breaking clang, and from clang options from breaking gcc. Clang 3.4 semantics are the same as gcc semantics for unsupported flags. For unsupported warnings clang 3.4 returns true but shows a warning and gcc shows a warning and returns false.
