behind runtime detection, the elf attributes should be suppressed.

This allows tools to know that the final built binary doesn't

0f2359b869 avutil/opencl: is_compiled flag not being cleared in av_opencl_uninit 
When OpenCL kernels are compiled, is_compiled flag is being set for each
kernel. But, in opencl uninit, this flag is not being cleared.
This causes an error when an OpenCL kernel is tried on different OpenCL
devices on same platform.

Here is the patch with a fix
