+Subject: [PATCH] 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.
