[libcxx] Whitelist inclusion of sysctl.h instead of blacklisting

Authored by bcraig on Jan 27 2016, 8:04 AM.



Instead of excluding all known operating systems that are not derived from BSD, I know include all operating systems that claim to be derived from BSD. Hopefully, that will make it so that this check doesn't need to change for every new operating system that comes along.

Where did the #Include <sys/param.h> come from?

sys/param.h is where BSD is defined (or not). If my research is correct, pretty much every *nix except for CloudABI has a sys/param.h.

CloudABI doesn't define unix, so stop blacklisting it explicitly and let the whitelist filter it out.

I plan on submitting this tomorrow morning (my time) so that I have lots of time to monitor build failures.
