LTO is supported by Clang compiler on OpenBSD => enable -flto during compilation (used with -prod for optimizations)

• OpenBSD clang manpage: https://man.openbsd.org/OpenBSD-current/man1/clang.1 => flag -flto
• Clang code OpenBSD.cpp, line 397 => OpenBSD::HasNativeLLVMSupport = true https://clang.llvm.org/doxygen//OpenBSD_8cpp_source.html#l00397

---

• Tests on OpenBSD/amd64 with clang v16 + prod => flag -flto used for compilation OK
