ncurses 5.6 - patch 20070217

+ fixes for $(TICS_LIST) in ncurses/Makefile (report by Miroslav
  Lichvar).
+ modify relinking of shared libraries to apply only when rpath is
  enabled, and add --disable-relink option which can be used to
  disable the feature altogether (reports by Michail Vidiassov,
  Adam J Richter).
+ fix --with-termlib option for wide-character configuration, stripping
  the "w" suffix in one place (report by Miroslav Lichvar).
+ remove "-ldl" from some library lists to reduce dependencies in
  programs (report by Miroslav Lichvar).
+ correct description of --enable-signed-char in configure --help
  (report by Michail Vidiassov).
+ add pattern for GNU/kFreeBSD configuration to CF_XOPEN_SOURCE,
  which matches an earlier change to CF_SHARED_OPTS, from xterm #224
  fixes.
+ remove "${DESTDIR}" from -install_name option used for linking
  shared libraries on Darwin (report by Michail Vidiassov).
