I'm not reverting this Ben.  The dependency those programs and
autoconf tests have is _dubious_ at best.

It means they were depending upon the libc5 checks passing, that's
rediculious and not something we should cater to.

If you really want it to work that linux/rtnetlink.h is included first
before sys/socket.h in userland, fix that specifically instead.  But
I believe such a dependency is reasonable and the userspace bits need
fixing.
