* A daring, but much needed change to clean up some of this mess.

Browse Source 
2001-06-01  Ben Elliston  <bje@redhat.com>

	* config.guess (i*86:Linux:*:*): Examine the list of supported
	targets, not the list of supported emulations when capturing
	the output of "ld --help".  This causes problems on systems
	where GNU ld is built with support for all targets. Adjust
	cases in the switch accordingly.

	* config.guess: Other small Linux cleanups. Remove unnecessary
	logic for setting $VENDOR, since UNAME_MACHINE will always be
	i*86 in this case.
