[Beignet] [QA 2014/02/13] Status of Piglit test cases

[He Junyan]

hi Yi:

I login to your PC and find that it should be the problem of ICD lib.
I notice the when the program crash, the clCreateContext API in our
beignet lib is not really be called. So the dl_open address of
clCreateContext in ICD lib seems change to wrong address. 

I try to delete the /lib64/libOpenCL.so.1 in your PC and link it to
/usr/local/lib/beignet/libcl.so
This case can pass successfully.
I can not find the ICD source code on your machine so I can not locate
where the problem is in ICD now.
