This problem occurred in the environment described in bug 348535, soon after having skipped the `./bootstrap-prefix.sh $EPREFIX/tmp coreutils' step. The two problems might be independent, at least there is no obvious (to me) similarity. It seems that a sufficient workaround is to skip the initial build of 'tar'. A Gentoo Prefix 'tar' package gets emerged later on, in the `emerge --oneshot tar' step.

I think the updated bootstrap snapshots will help here, as we're currently at version 1.26.
