So admittedly this isn't using a cross compiler rather than a linux-user
powered docker image but I first of all had to:

  mkdir arm-linux-user/tests

And then running:

  docker run --rm -it -v /home/alex/lsrc/qemu/qemu.git/:/src --user=alex:alex -w /src/arm-linux-user/tests debian:armhf make -f ../../tests/tcg/arm/Makefile

yielded:

  ../../tests/tcg/arm/Makefile:12: /home/alex/lsrc/qemu/qemu.git/rules.mak: No such file or directory
  make: *** No rule to make target '/home/alex/lsrc/qemu/qemu.git/rules.mak'.  Stop.

Which I guess is a relative vs absolute problem. I wonder if there is a
way to make it cleaner in the event of these re-locations?

BTW running:

  docker run --rm -it -v /home/alex/lsrc/qemu/qemu.git/:/home/alex/lsrc/qemu/qemu.git/ --user=alex:alex -w /home/alex/lsrc/qemu/qemu.git/arm-linux-user/tests debian:armhf make -f ../../tests/tcg/arm/Makefile

Gives:
