Yes. I use
  clang -emit-llvm -ccc-host-triple arm-unknown-linux-gnu -I /..arm../include/
to generate LLVM bitcode files for ARM. llc then automagically knows to
generate ARM assembly, and ARM binutils take it from there.

Dunno. Last time I looked, the documentation of clang's command line flags
disagreed with reality, and the -ccc-host-triple flag wasn't documented
anywhere. This might have changed in the meantime.
