+	  This option enables Link Time Optimization (LTO), a mechanism which
+	  allows the compiler to optimize between different compilation units.
+
+	  This can optimize away dead code paths, resulting in smaller binary
+	  size (if CC_OPTIMIZE_FOR_SIZE is enabled).
+
+	  This option is not available for every architecture and may
+	  introduce bugs.
+
+	  Currently, when compiling with GCC, due to a weird bug regarding
+	  jobserver, the final linking will not respect make's --jobs argument.
+	  Instead all available processors will be used (as reported by the
+	  nproc command).
+
