修改 python3.5.10/Makefile.pre 和 python3.5.10/ Makefile.pre

OPT= -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes还是相同的错误，如果Setup 不把ssl注释，错误1049错误，即

经过1天的研究，到处查资料，到处问没人回答，通过自己排列组合，不断尝试，终于成功，但道理仍不明白
1. config 如有错误，是否要clean
2. make 或 make install 有错误，是否要重新 clean,重新 config
3. --with-openssl 和 Moudles/Setup 注释到 SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
也有路径，有何不同，哪个为准
4. OPT= -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes 其中的 O2 和 O3 是什么意思
5. 如何调试coredump，C语言不懂
