ncurses 5.7 - patch 20090104

+ modify gen-pkgconfig.in to eliminate a dependency on rpath when
  deciding whether to add $LIBS to --libs output; that should be shown
  for the ncurses and tinfo libraries without taking rpath into
  account.
+ fix an overlooked change from $AR_OPTS to $ARFLAGS in mk-1st.awk,
  used in static libraries (report by Marty Jack).
