	Passing in the string "default" or setting the environment
	variable to "default" will cause the first entry in the target
	list to be returned, and "target_defaulted" will be set in the
	BFD.  This causes <<bfd_check_format>> to loop over all the
	targets to find the one that matches the file being read.
