Ah, OK.  That's good to know!

I've committed this patch in 7eaa2f24ea77cddbb4bbc2d6a6905673a36f8f99 on
master.  I've also reverted 4fff5ab24126a152b50c036b9bf8dc6f2740f094 in
commit b50341dba9811c048bed852c0279b828c7ddba66 on core-updates.  I
think we should be good to go to try building powerpc64-linux-gnu
bootstrap-tarballs now!

I confirmed that this commit on master would not cause dependents of
libffi to be rebuilt by verifying that the derivation for one of its
dependent packages, guile, did not change before/after the change.
