So it worked before you upgraded to latest jethro? Maybe you can roll
back and/or check the changelog (git log x..y) for the code you just
pulled in?

Also, isn't there a lot of state in build/ beyond build/tmp/ that can
trip up a build? To be really clean, I'd go for full "rm -rf build/".
I'm kind of paranoid about those things :-)

Btw, I'm currently on Yocto jethro branches from mid february, not the
very latest. So maybe there is a real bug in latest jethro...
