Revert "hurd: Fix abi-tag, following ba90e05"
	and revert the corresponding part of ba90e05 which was making the fix
	necessary.

	* abi-tags: Revert ae20c9a: rename back gnu into gnu-gnu.
	* configure.ac, configure: Revert ba90e05: modify gnu-* host_os back
	into gnu-gnu, and update comment to refer to abi-tags.
