	* Makerules ($(common-objpfx)Versions.v.i): Depend on abi-versions.h.
	* Makeconfig (%.v.i, %.v): New implicit rules.
	(preprocess-versions): Variable removed.
	($(common-objpfx)shlib-versions.v.i): New target giving just the
	shlib-versions input files as dependencies.
	($(common-objpfx)soversions.i): Depend on that instead of the input
	files.  Use it as input instead of using a pipeline.
	(postclean-generated): Append soversions.i, shlib-versions.v, and
	shlib-versions.v.i here.
	* Makerules ($(common-objpfx)Versions.def.v.i): New target giving just
	the Versions.def input files as dependencies.
	($(common-objpfx)Versions.v.i): Likewise for Versions files.
	($(common-objpfx)Versions.all): Depend on that instead of the input
	files.  Use it as input instead of using a pipeline.
	($(common-objpfx)sysd-versions): Likewise with Versions.v.i.
	(postclean-generated): Append those .v and .v.i files here.
