What are you trying to do, exactly?  If you're trying to create an ARM
executable which uses LLVM libraries, note that you'd have to also
cross-compile LLVM first, using your new cross-compiler.  Otherwise, you're
trying to link ARM object files with x86_64 LLVM libraries, which aren't
compatible.

Note that I'm just guessing -- it's really hard to tell what's wrong without
complete information, e.g. exact command lines, your host machine, your
target machine, etc.
