Subject: [PATCH] meson: Set proper value for LIBCLC_INCLUDEDIR

LIBCLC_INCLUDEDIR is the location where mesa3d OpenCL implementation
will look for OpenCL "headers" on the target, when building the OpenCL
kernels.

The value returned by pkg-config for includedir is relevant when
cross-compiling, on the build machine. But in this specific case, we
really need a value that is valid on the target.

Those headers are installed by the libclc package in /usr/share so
that they are not removed by Buildroot target-finalize logic.

Based on the patch for autotools provided by Valentin Korenblit.
