[poky] Master stability update

[Richard Purdie]

We merged the features into master. I just want to highlight the status
of the following issues:

* pseudo problem causing failure of meta-toolchain and corruption of
certain file permissions - fixed in master

* the -live image issues some people and the autobuilder were seeing -
fixed in master

* the perf issue for linux-yocto-stable - fixed in master

The following are know issues with master:

* Using rm_work and switching machines to machines of the same
"multimachine" architecture breaks.

* When switching machines of the same "multimachine" architecture (e.g.
emenlow to atom-pc), some sstate packages are changing checksums when at
first glance they shouldn't (e.g. perl do_install). A quick scan of my
sstate directory:

$ ls *core2* | sed -e 's#core2-2-.*_#core2-2_#' | sort | uniq -cd | grep -v siginfo

yields:

which isn't too bad but shows there are some issues creeping in there.
These need investigating and fixing, there is a strong rpm theme going
on there. Also note this was just a minimal image, sato will likely
reveal other issues.

Cheers,

Richard
