[yocto] linux-yocto: bitbake restarts with do_fetch after a -c configure

[Darren Hart]

I was having some trouble doing some iterative kernel development and
noticed that bitbake was restarting with do_fetch no matter what stage I
had completed with the previous command. I thought it might be
triggering on a source change, but just running the following without
any other changes had the same result:

$ bitbake linux-yocto -c configure
...
$ bitbake linux-yocto
$ bitbake linux-yocto

This prevents any sort of iterative development as the unpack and
subsequent steps undue any local changes to the source tree. This
appears to be a regression.
