+Subject: [PATCH] linux.gcc: Fix cross compilation error.
+
+When cross compiling on linux with gcc, the host gcc was used instead of
+the cross gcc to set compilation flags according to gcc version.
+
+When the cross gcc was in version 5.X and the host gcc in version 7.X,
+tbb was compiled with the -flifetime-dse=1 flag that does not exist on
+gcc 5.X.
