62e5b6b8b3 updating Mac installation instructions (#1443) 
In Mac, even after gcc is installed from homebrew, gcc and g++ still point to clang's version. 

Need to update the make/config.mk file to point the gcc and g++ compliers to the version installed by homebrew. 

More details can be found in this blog: https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_on_Mac_OSX?lang=en
