What was in the abigail::tools namespace got recently moved in the abigail::tools_unit namespace. I forgot to adjust the client code related to the archive support because that code is now compiled by default on my main hacking box. This patch fixes that. * tests/Makefile.am: tools/libtoolsutils.la is no more. * tests/test-write-read-archive.cc (main): Adjust. * tools/abiar.cc (extract_tus_from_archive): Likewise. Signed-off-by: Dodji Seketeli <dodji@redhat.com>
