Your test cases don't appear to involve any program headers. It's my understanding that `-O binary` is usually related to loadable programs, which have program headers. Indeed, at least one of your test cases talks about segments, but doesn't use them at all! Does your test case need updating?

You should probably update ConfigManager.cpp to indicate that the option isn't supported on other platforms.
