I've changed the configuration on my jenkins servers, so that now it
doesn't fail.

In case someone needs that as well then you need to use mode, uid and
git parameters for mounting tmpfs, e.g.

none /home/jenkins/oe/world/shr-core/tmp-glibc/ tmpfs noatime,nodev,nosuid,size=74G,mode=777,users,exec,uid=3004,gid=3004 0 0

where 3004 is uid and gid of jenkins user which is running the bitbake.



This change is still needed, because following exception shows so much about
bbclass sanity, that average user will get confused and eventually insane.
