Fixed a small issue in createAutoconfBundle.sh where we CD to `build/autoconf` folder before it's created. As result, we end up with `m4` and `autoconf` downloadable and unpacked folders in CWD.
By a chance, I did few other improvements: * colored logs for easier log reading * resolved `/../../` in the path to ease log reading. * `http://yum.oracle.com` was permanently relocated to `https`. ------------- Commit messages: - fixed createAutoconfBundle.sh CD to build/ before the folder is created. Added logs.
