Here are the steps I take to install CPU miner, my CPU doesn't support AES as well:
$ sudo apt-get install libcurl4-gnutls-dev automake build-essential git
$ sudo apt-get install libtool
$ sudo apt-get install libssl-dev
$ git clone https://github.com/LucasJones/cpuminer-multi.git
$ cd cpuminer-multi
$ echo "autoreconf -i" >> autogen.sh
$ ./autogen.sh
$ sudo CFLAGS="-march=native" ./configure
$ sudo make
$ ./minerd -a cryptonight -o stratum+tcp://xmr.minercircle.com:80 -u -p x
