Yes, that was not ported to sparc. It is not a big deal.

Adding to config/linux.m4 the following should fix this configure error:

         arm*-*) LINUX_SRCARCH=arm;;
+     sparc*-*) LINUX_SRCARCH=sparc;;
         *) AC_MSG_ERROR([architecture ${host} not supported]);;


Compile and test if that works. An quick and easy test is "lxc-execute 
-n foo /bin/bash"

Also, a modification to the lxc_clone function in src/lxc/namespace.c 
may be necessary.
