ncurses 5.9 - patch 20150221

+ capture define's related to -D_XOPEN_SOURCE from the configure check
  and add those to the *-config and *.pc files, to simplify use for
  the wide-character libraries.
+ modify ncurses.spec to accommodate Fedora21's location of pkg-config
  directory.
+ correct sense of "--disable-lib-suffixes" configure option (report
  by Nicolas Boos, cf: 20140426).
