[oe] git master not updating

[Rod Whitby]

For those people who are using the FSO Makefile, it has now been updated
 to match the new unofficial undocumented instructions on how to use the
trial OE git repo.

"make update-makefile" followed by "make setup-openembedded" will
automatically migrate your build environment to use the
org.openembedded.dev branch.

[Now let's see how quickly all the other places on the internet where
the old instructions live are updated, and how many more bug reports and
questions we get from people following them and not having a means to
automatically migrate to the new way of doing things.]
