Bruce Ashfield 4ed858bc76 linux-yocto/3.10: fix long perf compile times 
perf's builtin-sched.c triggers extremly long build times on some
architectures due to gcc 4.7+ var-tracking functionality.

To fix this, we can cherry pick the 3.12 commit:

  f36f83f94 [perf sched: Move struct perf_sched definition out of cmd_sched()]

With this change build times are reduced from 15 to 20 minutes for qemuarm to:

  real    2m19.940s
  user    1m35.438s
  sys     0m11.165s

For kernel's that are not carrying this patch, the following can be added
to the perf recipe to also fix the issue:

README 

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most everything else should be sent to the OpenEmbedded Core mailing list.  If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
    openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix
      of oe-core and poky-specific files.
