[PATCH] Don't configure GDBtk unless it is there

[Andrew Cagney <ac131313@cygnus.com>]

FYI,

I've checked in the attatched.  It stops GDB trying to configure Insight
when there there are no Insight sources to build.

	* configure.in (ENABLE_GDBTK): Delete variable.
	(enable-gdbtk): Only enable gdbtk when there is a GDBTK directory.
	* Makefile.in: Update.
	* configure: Regenerate
