we can't actually use __FreeBSD_version provided by <osreldate.h>

it a hard error if -pthread is provided on the command line and gcc
was configured with --disable-threads (this will help avoid bug
reports from users complaining about threading when they
misconfigured the gcc bootstrap but are later consulting FreeBSD
manual pages that refer to the mythical -pthread option). */
