Not trying to be inflammatory, but if you guys are really serious about doing this, you could consider using the LLVM integrated assembler. It is built as a library and is easily separable from the code generator (codegen depends on the assembler, not the other way around). It would be much much simpler to integrate than the binutils assembler.
Some information is here:

It currently supports darwin x86 quite well. ELF/PECOFF and ARM support are in active development. It sped up clang by ~10% at -O0 -g.
