cpuminer build fix for Linux Mint 15 Cinnamon

I ran into trouble building cpuminer in Linux Mint 15 (64 bit) Cinnamon. Everything was fine until I got to configuring CPFLAGS. It wouldnt take and it was annoying because that is the last step. Here is my solution. This can be done whether your are currently stuck on this step or you are about to do the entire build.

sudo apt-get install make automake build-essential git
  sudo apt-get install libcurl4-openssl-dev
  git clone git://github.com/pooler/cpuminer.git
  cd cpuminer
  ./autogen.sh
  ./configure CPPFLAGS=''
  make

Notice the standard build for Ubuntu based distros contains ./configure CPFLAGS="-03". WHen it wouldnt go any further I just checked the config log file in cpuminer main folder, plugged in the CPPFLAGS='' command and Bingo!

A few noobs trying to cpu mine FeatherCoins were getting frustrated in the chat so I figured I would see if I could get it to work.

Rock on, happy mining
