configure: support HAVE_BSD_SYSCTL option
On BSD-compatible systems some information such as the number
of available CPUs may only be available via the sysctl function.
Add support for a HAVE_BSD_SYSCTL option complete with autoconf
support and include the sys/syctl.h header when the option is
enabled to make the sysctl function available.
