+ and the introduction of the internal arch-15 itself.
+ These are only needed for oracular and older,
+ and are included in binutils for a while.
+
+ * Other architectures are not touched and affected, since only s390x
+ specific files are modified (except the doc file as/doc/as.texi on top).

alternative for "arch15".
