I wonder whether we should signal this somehow. I mean, have something
like this:
#else /* !CONFIG_LINUX */
g_debug("Stats reporting available only for Linux");
#endif /* !CONFIG_LINUX */

A counter argument is that if fopen() above fails then -1 is returned
without any error/debug message reported. And stats fetching is best
effort anyway.
