[PATCH RFA] Clean up GDB's packaging, add support for dejagnu, insight, ...

[Andrew Cagney]

Hello,

The attatched patch modifies the top level Makefile.in so that:

	o	the ``taz:'' / ``do-tar-bz2:'' targets
		build a PACKAGE instead of a TOOL.
		By default PACKAGE=$(TOOL)
		The PACKAGE determines the archive
		name while the TOOL determines the
		top level directory containing
		versioning etc.

	o	Removes GDBTK stuff from the GDB
		net relese

	o	adds rules to build ``dejagnu''
		``gdb+dejagnu'' ``insight''
		and ``insight+dejagnu'' releases

Ok?

	Andrew
