perf cross compilation on yocto-linux for ARM fails

[Suresh Nagarajan]

perf cross compilation on yocto-linux for ARM fails.  I've seen posts on 
this failure on internet but no where a detailed info is given on what was 
the fix (or if there is a fix yet)

using yocto package, I have run into issues.. 

Here are the steps to run into the issue
$ cd ~
$ git clone http://git.rocketboards.org/poky-socfpga.git  
$ cd  poky-socfpga/
$ git checkout -b <test_branch> ACDS14.0_REL_GSRD_PR
$ source ./altera-init build
$ bitbake perf 

Note: replace <test_branch> with the name of the branch you want to use 
locally.


This fails with

you should create a recipe to build perf within the yocto framework.

ok. We use my version of perf internally so I had to write my own. Was 
not aware that there was a perf.bb file.

hmmm... did not hit that problem building ppc images on x86.

Does that lib exist in the image? If not is it in the build env sysroot 
(should be)?
