The OpenCL 1.2 is nicer but we can't always use it and on linux,
even if the CL_VERSION_1_2 exists, we can't trust it because distrib
sometimes have CL 1.2 headers with a CL 1.1 dispatcher.
So instead, we only assume we have 1.1 header and lib at compile time.
Then at run-time we do a dynamic lookup of the 1.2 symbols from the lib.
We also check if the actual selected platform does support 1.2 (you
could have a 1.2 dispatcher with a 1.1 platform implementation).
If both conditions are satisfied, then we dispatch the call to the 1.2
implementation and if not, then we dispatch them to a local fallback
implementation of the functions (but limited to the functions we need)
It's not pretty but it should work and it isolates all the hack magic
inside cl_compat.{c,h} and you just use the CL1.2 API normally outside
of it.
