  "message": "Enabling -O4 (link-time optimization) only if compiler/linker support it.\n\n- The -O4 option requires the linker to have bitcode support, currently for\n  clang this means using the gold linker and the LLVM-gold plugin:\n  http://llvm.org/docs/GoldPlugin.html.\n- Otherwise you get (confusing) \u0027file format not recognised\u0027 errors ala:\n  http://llvm.org/bugs/show_bug.cgi?id\u003d9897.\n- Adding explicit check for LTO support as at least some package installs of\n  clang on linux do not use the gold linker by default.\n\nChange-Id: I2a4c670e470d9b48da2a15b7e91a59fb4ad3e8ad\n",
