+Subject: [PATCH] mesa-clc: add an option to force inclusion of OpenCL headers
+
+Currently mesa-clc bundles OpenCL headers from Clang only if the static
+LLVM is used (which means Clang / LLVM are not present on the target
+system). In some cases (e.g. when building in OpenEmbedded environemnt)
+it is desirable to have shared LLVM library, but skip installing the
+whole Clang runtime just to compile shaders. Add an option that forces
+OpenCL headers to be bundled with the mesa-clc binary.
