Mark bugs fixed since portage-2.1.9.42 as blockers of this bug.
Please pull this one from the mirrors immediately. It just installs files consisting of zeros instead of the binaries. I just trashed my system, because sys-apps/portage-2.1.9.46 installed sys-apps/coreutils-8.11 (after upgrading itself) and the result was an unusable system (because all the coreutils binaries are just files full of zeros).
Sorry. This is a problem of the sys-apps/coreutils-8.11 ebuild and not of portage.
