[meta-fsl-arm] libmcc sysroot issues

Dear all,
I'm experiencing sysroot issues with the libmcc library on the latest 
revision of branch dizzy (2014-12-30, commit 
7539a694f3d01f1ab5162bfee16b0327f827c4f7). Not all required files are 
populated into the SDK, so the library cannot be further used in the 
application development without manually manipulating the sysroot.

First of all, compilation of such application fails on the dependency on 
<linux/mvf_sema4.h> include file, coming from <linux/mcc_config.h>. The 
mvf_sema4.h file is a part of linux-timesys (3.0.15) kernel (directory 
include/linux), and should be located in /usr/include/linux in the SDK 
sysroot. I wanted to create a patch, but did not find an automated 
solution (as I already described at 
https://community.freescale.com/message/466383). This issue is not just 
my case, as you can find for example at the following link: 
http://developer.toradex.com/how-to/colibri-vf61-real-time-demo-%28xy-pen-plotter%29#Building_the_Qt_User_Interface

Second (after fixing the first issue manually), linking of such 
application fails on "-lmcc" flag, as it cannot locate libmcc.so 
library. In sysroot's /usr/lib, there is only libmcc.so.1.0, but a 
libmcc.so link is missing. After creating the link manually, the 
application can build and run as expected.

I would like to ask for a patch of these two issues, or at least for 
pointing me to some *brief* resource where I might learn how to create 
the patch on myself (i.e. what meta-data say yocto how to generate 
sysroots). Sorry, but studying the whole yocto documentation is just too 
long run. I spent whole day trying to find a solution with no success.

Best Regards,
Petr
