Looks good to me in general, though I would suggest someone who really uses bazel build to double confirm :)

We can always revert if this breaks downstream, but right now our CI is broken because https://github.com/tukaani-project/xz is quarantined.

LGTM, with the same recommendation as someone else made for someone who actually uses Bazel to try this out, but understood the desire to get it in soon.
