gettimeofday((void *)-1, NULL) implicates core dump on recent FreeBSD 11-CURRENT

[Doug Rabson]

As far as I can tell, POSIX doesn't require either EFAULT or any other
behaviour - the text in http://www.open-std.org/jtc1/sc22/open/n4217.pdf
just says, "No errors are defined". Our man page is wrong and any real
program which relies on gettimeofday not faulting when given bad inputs is
broken.
