[OpenCL] Disable C99 standard lib functions
The library functions defined in the C99 standard headers
are not available (OpenCL v1.2 s6.9.f).
This change stops treating OpenCL builtin functions as standard C lib
functions to eliminate warning messages about printf format string.
Patch by Liu Yaxun (Sam)!
