[PATCH] Check for ncursesw first when searching for "tgetent"

[Sergio Durigan Junior <sergiodj@redhat.com>]

Commit 5007d765ae09c10c7f3b18bb16841b9d2d59e181 ("Allow linking GDB
with ncursesw") modified our configure.ac and included the check for
"ncursesw" when searching for "waddstr".  However, there's one more
place where we should check for "ncursesw" first:

  AC_SEARCH_LIBS(tgetent, [termcap tinfo curses ncursesw ncurses])

This patch changes the order of the libraries to be searched when
looking for "tgetent", and puts "ncursesw" before "curses ...".

This is another patch we carry on Fedora GDB.

gdb/ChangeLog:

	* configure.ac: Check for "ncursesw" first when searching for
	"tgetent".
	* configure: Regenerate.
