[yocto] Release candidate build for Yocto Project 2.5 RC1

[Burton, Ross]

Hi,

We have a build ready for QA for the Yocto Project release 2.5,
release candidate 1.  As with the M3 this was built on the new
autobuilder so the announcement is happening manually again.

The release is available at:

http://autobuilder.yoctoproject.org/pub/releases/yocto-2.5.rc1/

The build results can be seen at:

https://autobuilder.yoctoproject.org/new/#/builders/30/builds/45

The eclipse-plugin-neon build failed, but it was re-ran and built
successfully so this isn't a problem.

Please QA this as soon as possible.

Regards,
Ross
