[OE-core] krogoth status

[Richard Purdie]

It was mentioned to me that krogoth seems stalled. I had a look at the
status and I think we were doing well but the test build failed in
multiple ways and then we lost momentum. I have just:

* merged Armin's krogoth-next branch
* backported a grub-efi gcc6 fix
* backported a selftest fix
* updated the meta-qt4 krogoth branch to add in some gcc6 fixes
* triggered a new test build on the autobuilder

We'll see what happens to this build...

Cheers,

Richard
