[yocto] New warning(s)

[Gary Thomas]

When I run bitbake using layers that are not GIT repos, I'm
now getting a lot of messages like this:
   fatal: Not a git repository (or any parent up to mount point /raid)
   Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

This seems to be new (I've built from such trees many times
before with no such messages) and it hardly seems "fatal".
The messages apparently are coming from 'git' (I tested with
git version 1.9.1 and 1.7.11)

Why the change?
