Created attachment 848197 [details] build.log build log and emerge --info
I looked into the issue on my system: /var/tmp/portage is on TMPFS of a vanilla kernel. It doesn't support xattrs. That's probably why the tests fail. It only happens with -r1, because plain 0.8 (and earlier?) was not running the tests.
Please ensure that PORTAGE_TMPDIR has xattr support enabled.
