Do you have that change for lang/rust/Makefile?  If so, my point was
that if the problem is a parallel build, one way to test that hypothesis
is to make the build serial and see if the sporadic failures go away.
But with

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

in the Makefile, MAKE_JOBS will be used by Cargo even if
MAKE_JOBS_SAFE=no.  So, you'd have to explicitly undefine MAKE_JOBS, or
set it to 1, in order to test this hypothesis.  If the failures go away,
then you'd have a better idea of where to look in order to track down
the problem.
