Require automake 1.7 or higher. Fixes problem reported by Gilad
Arnold where Gentoo Linux tries to be too smart and chooses automake
1.5, which doesn't set @PACKAGE@, leading to include files being in
$(prefix)/include rther then $(prefix)/include/quagga.
(Since our makefiles rely on @PACKAGE@, they should have required an
automake new enough to set it.)
