The OS variable is only for the olsrd build system. Each system's compiler
sets relevant system detection macros. So GNU/Linux's gcc sets __linux__ and
__gnu_linux__, Android's gcc sets __linux__ since it uses the Linux kernel,
but not __gnu_linux__ since Android is not GNU nor UNIX. Mac OS X's gcc sets
neither, etc. etc.
