If you have a multilib GCC installed, it's as simple as adding -m64 to the commandline. The compiler should complain if it is not built with multilib support.

In order to link, you'll need all the 64-bit counterparts of the standard libraries. If your distro has a multilib GCC, these should also be in the repositories.
