  xz is quite a common format for software to be distributed in nowadays
because of its size reductions.  With this patch, here is the result
on the master branch at db716e3b15912b7162def1faa704eb7823bbf34:

.rw-r--r--  406M sam   8 Nov 07:27   libabigail-2.2.tar.gz
.rw-r--r--  348M sam   8 Nov 07:26   libabigail-2.2.tar.xz

	* configure.ac: add dist-xz to AM_INIT_AUTOMAKE.
	* Makefile.am: adjust $(TARBALL) to new extension.
	* Makefile.am: pass XZ_OPT="-0" for distcheck-fast.
