Fix MinGW TUI build 

gdb/
2015-01-22  Eli Zaretskii  <eliz@gnu.org>

	* gdb/tui/tui.c (tui_enable) [__MINGW32__]: If the call to 'newterm'
	fails with the 1st arg NULL, try again with "unknown".  Don't test
	the "cup" capability: it isn't supported by the Windows port of
	ncurses, but the Windows console driver is still capable of
	supporting TUI.
