[LLVMdev] Building LLVM 2.7 on OpenSolaris

I'm interested in using LLVM for compiling to x86_64 native code  
(ELF64), so I selected 'x86_64' as the architecture. I added 'host'  

The '--with-built-clang' selection is for building the Clang LLVM C  
compiler instead of using a gcc front end. I placed the Clang  
distribution in './tools/clang'.
