Copy config.h to faad2-config.h.  Modify systems.h to refer to
faad2-config.h, and install faad2-config.h.  This situation is
discussed here:
http://lists.gnu.org/archive/html/automake/2000-10/msg00114.html

Remove the undef of PACKAGE and VERSION, and add a 3rd non-empty
argument to AM_INIT_AUTOMAKE.  This situation is discussed here:
http://lists.gnu.org/archive/html/automake/2000-10/msg00108.html

Modify the condition from HAVE_GLIB_H to __G_LIB_H__, which was
easier because faad2 doesn't depend on glib.

Bump pkgrevision.
