(toplevel) Don't look for unprefixed tools unless they're appropriate


Tested on i686-pc-linux-gnu with a Canadian cross.  Now if the 
prefixed tools can't be found (and the unprefixed tools are incorrect), 
the tool values default to blank, which will cause entirely different 
errors.  (Heh.)

I'd rather have them default "correctly", but that's somewhat less
trivial, and it's really only useful for people who 'configure',
relocate, and then 'make', which doesn't work anyway.

	* configure.in: Don't default to unprefixed tools unless
	the native tools will work.
	* configure: Regenerate.
