Linaro OE RPB warrior updates

hi,

i've started to push some updates about OE warrior for our Linaro builds.

The branch warrior was added to meta-rpb, meta-96boards, meta-qcom, meta-linaro, meta-backports.

I have added a 'warrior' branch to the oe-rpb-manifest as well, see: https://github.com/96boards/oe-rpb-manifest/commit/dd60a2322845adb9cfe7e82e6...

Some layers still don't have a warrior branch, in which case we use master.

I have submitted a change to start build based on warrior..

Let's see how things go with this new branch!

cheers nico
