Hmm, looking at lang/rust/Makefile in current, I see

  # cargo defaults to using the number of available CPUs
  MAKE_ENV+=              CARGO_BUILD_JOBS=${MAKE_JOBS:U1}

which makes me wonder if MAKE_JOBS_SAFE=no is not enough, and you'd
actually need to set MAKE_JOBS=1 for it to have the intended effect?
