ar "emulations"


I noticed this the other day when looking at a bug report regarding
ar for an aix target.  Presumably this loop was modelled on a similar
loop in gas/configure.in, but it doesn't make sense here.  ar
doesn't support multiple emulations like gas does on some targets.

	* configure.in: Don't invoke configure.tgt on $enable_targets.
	* configure: Regenerate.
