This function is essentially just four lines of shell, that for some reason was
written in Python.

I suspect this will break in the various signature checks and cause
rebuilds when things shouldn't.

http://git.yoctoproject.org/cgit.cgi/poky/commit/meta/?id=f07b7c0da1748afc35fbb2ead7ae10ec66c7c428

hints at why:

"It needs to be a python task to avoid lots of shell exported variables as dependencies."

which should of course be a comment in the code.

I wish we had a better way to control exported variables to shell tasks
which would be a better fix but right now we don't.

Cheers,

Richard
