fix the hard number in paddle version
Created by: tensor-tang
现象：
function version(){ echo "PaddlePaddle 0.10.0, compiled with" echo " with_avx: ON" echo " with_gpu: OFF" echo " with_mkl: ON" echo " with_mkldnn: 1" echo " with_double: OFF" echo " with_python: ON" echo " with_rdma: OFF" echo " with_timer: OFF"
存在一个数字1，需要改掉。
原因是这里AVX2_FOUND的输出是1.
set(WITH_MKLDNN ${AVX2_FOUND})
