To be honest, I didn't read the specification thoroughly. The build of
libclc fails on FreeBSD if stddef.h is included, because a header pulled
by stddef.h defines variadic macros. Those macros are not supported by
OpenCL according to clang.

I then asked on the #llvm IRC channel how I could exclude those macros
when building an OpenCL program. I have been told the problem rather
comes from libclc which shouldn't include any standard or system C header.

I then removed that #include, defined size_t and it built.
