ObjFW  History of build-aux/install-sh of 2cb48ceaf1d0c54a929080b17bcf0f994335809830ae6d0cbd8ae81dc9f2644b

This also reverts accidentally taking install-sh from NetBSD: It seems
that on NetBSD, pkgsrc replaces install-sh with its own version.
However, autoconf installs the version it ships with, which has been
replaced by pkgsrc in this case, which made me accidentally import
NetBSD's version. file: [1cccb4aa97] check-in: [42fb361c1b] user: js, branch: trunk, size: 15425 [annotate] [blame] [check-ins using] [diff]

This undoes our patches to config.sub. The next commit will re-add them,
so that this commit imports the unmodified files. file: [0170726bd8] check-in: [8ca4fcafcc] user: js, branch: trunk, size: 6760 [annotate] [blame] [check-ins using] [diff]
