If you do not have/plan any a.out programs, it is safe to use -DNOAOUT. But if you do, it's better to build it anyway. I'll explain _why_. a.out compatibility stuff (a.k.a. legacy support) compiles _current_ sources of all libraries, a.out rtld and old boot blocks in a.out format. So, for example, if libc was modified, building with legacy stuff will upgrade both ELF and a.out versions of libc.
