Hello
I came up with a different version and was about to post it when I saw yours.
I'll post mine as a reply to get your opinion.

Here is my comments on yours. Please not that I'm not a commiter.

I think it ok you don't #ifdef those

You could keep this test on a custom device

You don't need the else,
PIGLIT_CL_ENUM_NUM(cl_kernel_work_group_info, env->version)
already take care of it

You shouldn't fail here. The same way 
PIGLIT_CL_ENUM_NUM(cl_kernel_work_group_info, env->version)
ignore this flag, skip it and don't tell the user.
It doesn't expect it to be tested on version < 1.2 anyway

built_in_kernel_names = piglit_cl_get_device_info(env->device_id,
				                          CL_DEVICE_BUILT_IN_KERNELS);
is shorter

Would you be better to PIGLIT_WARN and skip test with built-in ?

PIGLIT_WARN ?
