There are two answers.  1) we're in the process of building a new llvm-native assembler.  When this is done, LLVM will be able to produce .o files without any other tools.   2) clang can talk directly to a system assembler if you teach it how to (by defining a "ToolChain" for your platform).  In the absence of that, it uses GCC as an abstraction layer to make it more portable.

In the short term, I'd recommend adding a clang toolchain description for your target.  This is pretty easy to do, ask on the cfe-dev list for more details.
