The proposal is to still have it hooked up to t/helper/test-reftable.c,
the build system, and t0032-reftable-unittest.sh.

So we'd build and test it on all platforms, getting that working in some
stable fashion would already be a big step forward.

What we wouldn't get right away is the series as of things like
0a0d5fe74d4 (refs: RFC: Reftable support for git-core, 2021-08-17),
i.e. hooking up refs/reftable-backend.c, changes to refs.[ch], running
reftable with some mode of "git init".

As discussed elsewhere that step would currently fail with some tests
failing, but most/all of those failures are due to the integration of
the reftable library into git, not failings of the library itself or the
reftable format.
