I don't see anything obvious in the code below.  Search the build logs for 
libXrandr, libXext for references to /usr/lib or similar.

Are you using the stock oe-core toolchain?  If so there is a patch that detects 
and attempts to poison (cause an error) usage of system directories while cross 
compiling.  If you are using your own toolchain, a vendor toolchain, or a 
CS/Mentor toolchain.. then you may not have this patch and the system won't auto 
detect that type of contamination.

Check the version of glibc on your host, is it 2.14 (or newer)?  Then check the 
version of eglibc in your build, I assume it's 2.13...

if the above is true, that would seem to indicate that it is likely host 
contamination...

The other tool you can enable is "swabber", in your local.conf in the 
"USER_CLASSES" you can enable "image-swab".  Swabber can be a -very- slow 
process, but is a good last resort for identifying host contamination.

It's been a while since I used swabber, and I don't remember how.  I've been 
looking and I'm having problems finding the documentation on setup and usage of 
swabber.  You may need to join and ask on the Yocto Project mailing list for 
help on that.
