openssl does not have a number assigned

在openssl中新增了几个对外的API，make时，提示如下错误（或者新增的接口没有编译到libssl.so或libcrypt.so）：

Warning: *** does not have a number assigned
Warning: *** does not have a number assigned
Warning: *** does not have a number assigned
Warning: *** does not have a number assigned

解决办法：

（1）利用config脚本，产生一个Makefile
#./config
（2）执行下面的命令，自动把新增的接口更新到util/libssl.num和util/libcrypto.num
#make update
