This makes executable semantics build and pass tests for me without installing either Bison or Flex. We just use the primitive toolchain with the existing genrule as the packaged rules don't quite fit how we're building and organizing the code. Currently, this points at forks of the upstream rule repositories while PRs I have sent there are going through, but this should be functional for now and there doesn't seem to be any reason to wait for those PRs to go through.
