The i386 build seems to have problems with illegal instructions.

I guess it's related to crypto2: https://github.com/shadowsocks/crypto2/blob/master/src/blockcipher/aes/x86.rs#L13

For some old x86 devices without AES instructions, we may need to disable the ASM here.

To simplify the logic, we can totally disable assembly acceleration on armeabi and i386 build.
