(toplevel patch) rename buildargs,hostargs,targargs

[Nathanael Nerode <neroden@twcny.rr.com>]

This renames some shell variables (buildargs, hostargs, targargs) to the same 
names used for the substitutions into the Makefile, to clear the way for 
replacing the sed statements with AC_SUBSTs.  Tested on i686-pc-linux-gnu, 
generated Makefile unchanged.

	* configure.in: Rename (buildargs, hostargs, targargs) to 
	(build_configargs, host_configargs, target_configargs).
