Bootstrap changes look fine to me, so r? libs

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

r=me for the libs parts, but I'd like somebody more familiar with bootstrap to make sure there isn't anything missing.
