[yocto] [PATCH] In Yocto 2.7 powertop package is broken.

[Kaz Kylheku]

Hi all,

Via a .bbappend file in my own layers, I added the following patch to
build powertop, which is enabled when tools-profile is added to
EXTRA_IMAGE_FEATURES.

* recipes-profiling/powertop/files/posix-path-max-not-defined.patch:
Patch for build issue. The C++ code needs to including <limits.h> which
defines the POSIX PATH_MAX preprocessor symbol.
