Hey! I have tested LTO in Mojave 10.14.1 (my macbook).

With DENABLE_LTO=ON

cflags: 
-Wno-unknown-pragmas-fexceptions-funwind-tables-fno-omit-frame-pointer-fno-stack-protector-fno-common-msse2-Wno-parentheses-equality-Wno-tautological-compare-Wno-varargs-Wno-implicit-fallthrough-isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk-flto=thin

third_party/luajit/src/lib_aux.o: LLVM bitcode, wrapper x86_64

Without DENABLE_LTO=ON

third_party/luajit/src/lib_aux.o: Mach-O 64-bit object x86_64
