I wonder if we can get around this one by building the static libraries in a temporary directory instead of within the tools/ directory (surely we're allowed to have symbols like this when linking against system libraries?)

This one is a new change from r-devel and I don't think we'll be able to get around it (well, there are workarounds, but none that are in good faith with the spirit of the rule). The only way to avoid this would be to require a user to build/install a suitable version of Abseil themselves, and that is not trivial for the average user.
