re PR regression/47836 (Some Cross Compiler can't build target-libiberty or target-zlib)

	PR47836
	PR23656
	PR47733
	PR49247
	* configure.ac (target_libraries): Remove target-libiberty.
	Remove case-statement setting skipdirs=target-libiberty for
	multiple targets.  Remove checking target_configdirs and
	removing target-libiberty but keeping target-libgcc if
	otherwise empty.
	* Makefile.def (target_modules): Don't add libiberty.
	(dependencies): Remove all traces of target-libiberty.
	* configure, Makefile.in: Regenerate.
