给 gmtls/gm_handshake_client_double.go 加上 // +build !single_cert 之后， 编译仍然报错：

~/code/github.com/tjfoc/gmsm (master) $ go build -tags single_cert ./...
# github.com/tjfoc/gmsm/gmtls
gmtls/auto_handshake_server.go:172:10: cannot use []Certificate literal (type []Certificate) as type *Certificate in assignment
gmtls/auto_handshake_server.go:175:26: invalid operation: hs.cert[0] (type *Certificate does not support indexing)

gmtls/gm_handshake_server.go 和 gmtls/gm_handshake_server_double.go 中 的 type serverHandshakeStateGM struct 的 cert 字段定义不一样。 一个是 cert *Certificate 一个是 cert []Certificate
