+Subject: [PATCH] tbb: Enable cross-compilation.
+
+This patch replaces hardcoded value for CPLUS and CONLY with $(CXX) and $(CC).
+So, by defining CC= it is possible to cross compile this library using a
+cross-compiler.
+
+This patch was originally written by:
+Marcin Juszkiewicz <marcin.juszkiewicz@linaro.org>
+and taken from:
+https://github.com/intel/luv-yocto/blob/3b0688bc9a5e8d52b6ca461b15fb4abd3eaaf7a8/meta-oe/recipes-support/tbb/tbb/cross-compile.patch
