Upstream configure.ac has this check:

AC_SEARCH_LIBS([pthread_atfork], [pthread], [],
	AC_MSG_ERROR(pthreads support is required to build ivykis.))

(It used to check for pthread_create, but on Linux that would lead to
the earlier -lrt dependency (for clock_gettime()) implicitly pulling
in -lpthread but not libpthread_nonshared.a.)
