	scripts directory.  Pass move-if-change to awk.
	(common-generated): Add $(version-maps) and sysd-versions.
	* versions.awk: Moved to...
	* scripts/versions.awk: ... here.  Use move-if-change to void
	touching unchanged files.  Print "version-maps = ..." instead of
	"all-version-maps = ..." and without $(common-objpfx).  Explain
	expected variable names.
	* Makefile (distribute): Updated.
