Add support for Linux for SPARC distribution host and template

Browse Source 
Linux for SPARC is a free community Linux distribution for SPARC hosted by Oracle. See : https://oss.oracle.com/projects/linux-sparc

While the distribution is based on Oracle Linux it does have some differences and since it's not actually Oracle Linux I decided to add a separate template rather than having the Oracle Linux template also support Linux for SPARC.

This patch adds the lxc-template for Linux for SPARC and it also adds Linux for SPARC in the configure.ac as a distribution target to build.
