'CC="icc -mmic" ./Configure shared linux-generic64' works in 1.0.0. It's better than modifying Configure. I just didn't think of it. 

But it doesn't work in 1.0.2, getting some link error:
../libcrypto.so: undefined reference to `rc4_md5_enc'

And linux-x86_64 won't work here, since it uses some instructions not supported by MIC.
