[commit] Fix configury stuff for the DJGPP native build

["Eli Zaretskii" <eliz at elta dot co dot il>]

The DJGPP native build was slightly broken; the patches below fix
that.

Committed (to head).

2003-12-29  Eli Zaretskii  <eliz@elta.co.il>

	* configure.in: Set ac_cv_search_tgetent to "none required" for
	"*djgpp*" targets as well (DJGPP doesn't have termcap and doesn't
	need one).

	* config/djgpp/config.sed: Tweak to adapt to the changes in
	configury.

	* config/djgpp/djconfig.sh: Fix the test of unpacked
	distribution, since there's no gdb.cxx directory anymore.
