Fixes the following error when running devtool from a directory other
than the build directory (or the SDK base path when using within the
extensible SDK):
The BBPATH variable is not set and bitbake did not find a
conf/bblayers.conf file in the expected location.
Maybe you accidentally invoked bitbake from the wrong directory?
