Performance counters for Linux are a new kernel-based subsystem
that provide a framework for all things performance analysis. It
covers hardware level (CPU/PMU, Performance Monitoring Unit) features
and software features (software counters, tracepoints) as well.
To enforce the coupling between userspace and kernel, this
commit introduces perf as a subpackage of the linux-wrs tree.
perf is built directly inside the kernel tree (and hence picks
up all appropriate patches), but is packaged as a separate
utility that can be added to the rootfs and used to analyze
the kernel.

This change adds the ability to dynamicaly modify a git based
linux repo during the do_patch and do_configure changes.
The bulk of the work is done by the kern_tools, and the recipe
simply needs to add createme and modifyme scripts to go along
with the existing configme.

This base recipe implements support for building a git based
Wind River Linux kernel repository.
There are several restrictions in this first import:
- no patching (needs guilt)
- missing Wind River features (config audit, etc)
