Comment (by erikd):

 If I grab the llvm 3.5 release source tarball, apply the attached patch
 named `arm-lower-tail-calls.patch​` to the llvm sources, build them and
 the copy the new `llc` binary to `/usr/bin/llc-3.5` on my Debian system, I
 then get myself a working amd64-linux to armhf-linux cross compiler.
