broken pkg-config files

[Sven Joachim]

When configuring ncurses with the following options

./configure --enable-widec --enable-pc-files --with-ticlib=tic \
  --with-termlib=tinfo

and running "sh misc/gen-pkgconfig", it prints the following:

** creating ncursesw.pc
** creating panelw.pc
** creating menuw.pc
** creating formw.pc
** creating ncurses++w.pc
** creating tinfow.pc
** creating ticw.pc

And the ti{nfo,c}w.pc files are not only misnamed but also broken, since
they have -ltinfow and -lticw in the Libs: section, despite the
libraries being called tinfo and tic, respectively.

This seems to have been broken recently, probably with the
2011126/20111210 changes.

Cheers,
