Something like this should work as libc c is the first lib the system call
is searched if you look at code generated in configure
    AC_SEARCH_LIBS([pthread_create], [pthread],
        [test "$ac_cv_search_pthread_create" = "none required" ||
        LIB_PTHREAD_CREATE=$ac_cv_search_pthread_create])
    AC_SUBST([LIB_PTHREAD_CREATE])
